Abstract
People are ignorant of online privacy, they do not know how careless online usage has reduce their online privacy, not knowing how big tech companies like google are integrating their data (online information) and selling it for data-hungery companies, even unkomwing selling it directly or indirectly to scammers. Any personal data online is not safe so far it is not offline, and while the data are collected and integrated by these big companies like google, possibly can lead to date breaches which hackers can use to track victims into stealing bitcoin and other cryptocurrencies from him. Being careful of the browsers, search engines, VPNs, emails and many others such as being careful of the social media and the data we are sharing while online are all requisites to high level of privacy we can have online which can effectively protect us from hackers that want to steal bitcoin from us.

Introduction
People store keys to digital assets like bitcoin on phones, tablets and computers, this should make people to be conscious of their privacy, there are mistakes that can make hackers penetrate into victims computers and steal the keys which will be used to unlock the bitcoin by hackers and be stolen. Also, stealing any other sensitive data is possible which can lead to damages for victims. That is why privacy is very important in this digital era in order to be safe from hackers.

Many people use computers, tablets and phones to go online without knowing about privacy which is very important for self protection especially from attackers (scammers). People are making use of search engines the way they want, download any browser they wish, expose themselves online, not even conscious of how harmful these could to. Peoples' negligence about privacy makes them go online and be scammed, or resulting to malware download that can later results to bitcoin or other crypto wallets being hacked by attackers. Total Internet privacy is impossible, but you can get close by adjusting your online behavior — and a few of your privacy settings.

Phones, tablets, computers and other devices used to access the internet should be carefully used, there are many softwares that can unknowing make people not to have privacy, these softwares are mostly owned by big companies like google while there are some softwares needed on devices in order to have privacy. How we handle our devices generally is very important in maintaining privacy also.

1. Privacy-based browsers
The first to focus on are browsers, there are some privacy browsers but some browsers are privacy invaders, a good example of privacy invader browser is Chrome which is owned by tech giant called Google. Your web browser is the vehicle that carries you around the Internet to your desired websites. As such, it knows precisely what sites you have visited, how long you spent browsing them, and what you clicked on (or almost clicked on). Anyone who has access to your web browser can have a window into your income, your political leanings, and even your sexual preferences. This is why it’s so important to only use browsers you know will protect and improve your internet privacy. Below web browsers are best in keeping your browsing history safe from data-hungry tech companies and advertisers.

Firefox

The open source Firefox is the third-most-popular browser on the Internet, behind Google’s Chrome and Apple’s Safari. Developed by Mozilla, the Firefox team has improved the browser’s privacy protections in recent years. They have introduced advanced anti-fingerprinting and Enhanced Tracking Protection features this year, both of which make it much more difficult for third-party trackers to follow you around the Internet. If you primarily browse the Internet on your mobile device, Firefox Focus incorporates automatic ad blocking.

Tor browser

Tor is the best option if privacy is your utmost concern. The Tor browser is based on Firefox, but it has been stripped down and specially calibrated to run on the Tor network. When you use Tor, your traffic is encrypted three times and bounced between three Tor servers before it reaches your desired website. The encryption is handled in such a way that each server only has access to one set of instructions, so no server has access to both your IP address and the website you are visiting. This setup makes it impossible for Tor to keep any records about your online activity, and every time you close your session, the browser deletes your cookie cache and browsing history. The browser itself is formatted to prevent fingerprinting, and it blocks all kinds of trackers. Unfortunately, it also blocks a lot of plugins that websites rely on. For example, with its privacy settings fully activated, the Tor browser will block JavaScript. JavaScript can expose user information, but blocking it can make websites unusable. Using Tor can also mean performing endless CAPTCHA verifications when you try to access larger sites. Finally, the Tor browser is slower than other browsers because of the extra encryption.

DuckDuckGo

Unlike the other browsers mentioned above, DuckDuckGo does not have a standalone desktop browser, which means it is only a solution if you are browsing the Internet on your smartphone or tablet. With the DuckDuckGo browser, your browsing history never leaves your device. Deleting your entire browsing history is as easy as tapping a single button. It automatically blocks ads, stops third-party trackers, and ensures HTTPS encryption on all sites where that’s possible. One feature that does set it apart is the Privacy Grade it gives each site. This makes it easy for you to evaluate how much data each website collects from you, with and without DuckDuckGo’s protections, at a single glance.

2. Privacy Search Engines
The second to focus on are the search engines we are using, the reason why we should focus on search engines is discussed below using google as an example of privacy-invading search engines. Popular search engines like Google and Bing track your searches and other online activity.

DuckDuckGo

DuckDuckGo, unlike Google, utilizes the traditional method of “sponsored links” to display the advertisements. The ads are not focused on you but only the topic you are searching for – so there is nothing that could generate a profile of you in any manner – thereby respecting your privacy. Of course, DuckDuckGo’s search algorithm may not be the smartest around (because it has no idea who you are!). And, if you want to utilize one of the best privacy oriented alternative search engines to Google, you will have to forget about getting a personalized experience while searching for something. The search results are simplified with specific meta data. It lets you select a country to get the most relevant result you may be looking for. Also, when you type in a question or search for a fix, it might present you with an instant answer (fetched from the source). Although, you might miss quite a few functionalities (like filtering images by license) – that is an obvious trade-off to protect your privacy.

Qwant

Qwant is probably one of the most loved privacy oriented search engines after DuckDuckGo. It ensures neutrality, privacy, and digital freedom while you search for something on the Internet. If you thought privacy-oriented search engines generally tend to offer a very casual user experience, you need to rethink after trying out Qwant. This is a very dynamic search engine with trending topics and news stories organized very well. It may not offer a personalized experience (given that it does not track you) – but it does offer a rich user experience. Qwant is a very useful search engine alternative to Google. It lists out all the web resources, social feeds, news, and images on the topic you search for.

Search terms

When you think about how many times a day you enter a search term in Google, it’s easy to see how easy it would be for the company to build up a profile that strongly reflects what you do on a day-to-day basis. For example, we tend to search for a ton of topics related to our personal lives, all these information represent a pot of gold for advertisers. Advertisements are highly targeted to us based on our online activity because it is often highly reflective of our offline activity. Google and affiliate advertisers can create a very accurate profile of how each of us lives and market to us accordingly.

Why is Google tracking an issue?
Some people might find it helpful to be served ads on websites, within social media, and in emails that are tailored based on their personal tastes. Indeed, this is the basic premise upon which Google and similar companies justify their intense online tracking. They will typically say something along the lines of “to serve our customers better” or “to provide an improved experience for our users.”

What is really happening is that you, or your data at least, is a product that can be sold to advertisers or other third parties, whoever is the highest bidder, and this is a way that can leak your data to hackers. Many users find this intrusive and even downright creepy. Aside from knowing that someone is compiling a plethora of details about you so they can figure out how best to sell you products and services. The fact that all of this data is stored somewhere also makes it a target for hackers. And let’s not forget the potential for human error which could cause the data to be exposed inadvertently.

3. Encrypting Internet connection with VPN
A VPN encrypts your Internet connection from your device to the server owned by your VPN service provider. Using a VPN can help keep your web traffic safe from anyone monitoring the network at the local level: hackers, your Internet service provider, and surveillance agencies. A VPN will also mask your true location and IP address, allowing you to browse more privately and access geo-restricted content. A VPN will not, however, protect your web traffic against the VPN provider. That’s why it’s important to choose a VPN service you trust that does not keep logs of your activity. Download speed and privacy are usually the top considerations when looking for the best Tor VPNs. They can be used together to improve online privacy, but a provider that logs your activity or uses insufficient security will do just the opposite. The seven best VPNs for Tor and how to use them.

ExpressVPN Best VPN for Tor

Fastest VPN for Tor. Military-grade encryption. Accepts Bitcoin and has an onion site. ExpressVPN recently launched a .onion version of its website for users who want to anonymously make an account. The British Virgin Islands-based company accepts Bitcoin and sticks to a strict no-logs policy. Some non-identifying information is logged such as dates (not times), choice of server location, and total amount of data transferred each day. Cutting-edge encryption is used by default including 256-bit AES encryption, 4,096-bit DHE-RSA keys with perfect forward secrecy, and SHA512 authentication. ExpressVPN is highly rated, fast, user-friendly and has apps available for Windows, MacOS, Android, iOS, and Linux (command line).

Pros::
Fast and reliable
Accepts bitcoin
Has a .onion site
Leading security
No identifying logs

Cons:
Slightly more expensive

NordVPN Budget VPN

No logs, huge server network, strong security. Includes 30-day money-back guarantee. NordVPN gives users access to specialized servers pre-configured with Tor over VPN, which means all traffic is first sent through the VPN and then automatically redirected through the Tor network. This is great if you have apps other than an internet browser that you’d like to use with Tor. A double-VPN option is also available, which could be used with the Tor browser for a total of two VPNs and the Tor network, if you can tolerate the speed hit. NordVPN also boasts a strict zero logs policy and 256-bit AES encryption. The company accepts Bitcoin. Apps are available for Windows, MacOS, iOS, and Android.

Note that some experts object to Tor over VPN servers because NordVPN could hypothetically see what users are doing with their Tor connection by analyzing traffic before Tor encrypts it. NordVPN says it keeps zero logs, but if this is a concern, we recommend setting up Tor and the VPN independently.

Pros:
Onion servers
No logs
Strong security
Accepts bitcoin

Cons:
A few servers didn’t work

Surfshark

This privacy-conscious VPN comes packed with security features and allows you to pay in three different cryptocurrencies. Surfshark has 1,700+ servers in more than 60 countries, so you should be able to get a fast connection regardless of where you are in the world. Surfshark has a no-logging policy and secures your traffic with 256-bit AES encryption, a kill switch, and protection against IPv6, DNS, and WebRTC leaks. This service also has a couple of more advanced features. For instance, you can connect to multi-hop servers for even greater anonymity or speed up your other apps by using the split tunneling feature. Surfshark accepts Bitcoin, Ethereum, and Ripple payments, allowing you to sign up almost completely anonymously. Support is available 24/7 over live chat. Surfshark offers iOS, Android, Linux, MacOS, and Windows apps. It also works with supported routers but must be configured manually.

Pros:
Puts major emphasis on user security and privacy
Has no connection limit
Good speeds

Cons:
Some slow servers

CyberGhost

Excellent security, fast connection speeds, and zero logs. Our preferred budget VPN for Tor. PrivateVPN Simple to use, fast servers, and no logs. Also works well with streaming sites. CyberGhost doesn’t have any Tor-specific features, but it is the only VPN to earn a perfect score in our 2018 security and privacy assessment. For this reason, it pairs well with the Tor Browser. CyberGhost assigns each user a unique anonymous ID, and the email address you use to sign up is encrypted. This prevents third parties from connecting a users’ email address to their CyberGhost account. CyberGhost stores no identifying logs. The company is based in Romania, which has no mandatory data retention laws. Strong encryption, leak protection, a kill switch, and perfect forward secrecy are all included in the apps, even on mobile. Internet connection speeds are plenty fast enough to handle Tor traffic. Apps are available for Windows, MacOS, Linux, iOS, and Android. You may connect up to seven devices at a time.

Pros:
Advanced security
Zero logs
Bitcoin accepted
Fast

Cons:
No Tor-specific features

PrivateVPN’s

PrivateVPN’s website has a helpful guide on how to alter the OpenVPN configuration files included in the app so that outgoing internet traffic first passes through the Tor network, and then through the VPN—a setup known as “VPN over Tor”. If you want to use Tor to access sites on the clear web that don’t normally allow Tor connections, your IP address will be that of the VPN server, and the site won’t block you. Note that if you don’t want your ISP to see that you’re using Tor, it’s better to use a standard VPN connection with the Tor browser.

PrivateVPN offers great speeds and advanced security, plus a strict no-logs policy. You can connect six devices simultaneously.

Pros:
Zero logs
Fast servers
Strong encryption
Supports Tor-over-VPN

Cons:
Smaller server network

IPVanish

Advanced security, zero logs, and fast. Also popular with Kodi and torrent users. IPVanish is a speedy VPNs that doesn’t sacrifice privacy or security. A subscription gets you strong leak protection, unbreakable encryption, and a strict no-logs policy. IPVanish allows up to 10 simultaneous connections — more than any other provider on this list. IPVanish apps come with an obfuscation feature that disguises the encrypted VPN tunnel as normal internet traffic. You can opt to periodically change your assigned IP address at certain intervals, making you harder to track. It doesn’t accept bitcoin, though, so if you want to make an anonymous purchase, look elsewhere. Apps are available for Windows, MacOS, iOS, and Android.

Pros:
Fast speeds
Security is solid
No logs

Cons:
Bitcoin not accepted

4. Making your communications private
When communicating online, there are several ways companies or hackers can access your private conversations. Without encryption, an attacker monitoring the Internet would be able to see the information being transmitted to chat messages. Of course, the vast majority of online services use some form of encryption to protect the data traveling to and from their servers. But only a few tech companies encrypt your information in such a way that even the company cannot decrypt it. This kind of encryption is called end-to-end encryption (E2EE). Whenever possible, use services that offer E2EE and protect your privacy by default.

Using encrypted email(s)
Services like Gmail, Yahoo and Hotmail can scan your mailbox to collect data. Google, for instance, reads your purchase confirmation emails to build a database of everything you buy. If you don’t want your email service provider to have access to this kind of private information, you should switch to an end-to-end encrypted email provider. A good example of such emails is ProtonMail, messages between ProtonMail users are always transmitted in encrypted form. When a user sends an email to another ProtonMail user, the emails are encrypted on the sender’s device, and can only be decrypted by the recipient. All emails sent to/from a ProtonMail account (even if the other side is not using ProtonMail) are stored with zero-access encryption. Once a message is encrypted, only the account owner can decrypt it.
Increasingly, there are private alternatives to data-hungry companies, ProtonMail is a private alternative to Gmail. Instead of Google Drive, which can access and scan your files and documents, you could use encrypted cloud storage. For notes, Standard Notes is one end-to-end encrypted option.

Limiting information shared publicly
A lot of sensitive information about you is publicly available on the Internet. Some of it is a matter of public record, like court records, addresses, and voter registration. But much of it we put on the Internet voluntarily, usually via social media, like photos (often location tagged), family members’ names, and work history. Hackers can use these clues for social engineering and to answer security questions. Photos of you on social media can even be used to create deepfake videos of you. Almost all online services and Internet-connected devices have privacy settings you can adjust to restrict the amount of information collected and/or shared online. You can also add an additional email address to your ProtonMail account, which you can share publicly, instead of your primary email.

Limiting information shared privately
Online service providers can be vulnerable to data breaches, which can instantly compromise your privacy, sometimes in embarrassing ways. Even large services like Google or Facebook are not immune to data breaches. You can mitigate the privacy threat of data breaches by limiting the information you share with these services. For instance, you can use Google Chrome or Google Maps without logging into your account, or simply switching to a more privacy-friendly browser like Firefox. If the services themselves (and their third-party partners) are part of your threat model, switch to privacy-focused services that do not collect user data. With ProtonMail, accounts are anonymous (not linked to your real-life identity), and we collect as little user information as possible.

5. Be vigilant of phishing attacks
A phishing attack attempts to steal your account credentials or infect your device with malware by tricking you into clicking on a link or downloading an attachment. Phishing attack can be through email, or any other means like impersonation, clicking on unsecured links or visiting a site packed with malware's can all lead to phishing attacks. To protect yourself from phishing attack:

1. Do not click on links you do not authorize
2. Delete old apps on your devices
3. Be careful of who you are chatting with on social media , especially, strangers.
4. Not click on unsecured sites, unsecure sites are the http sites that do not have SSL certificate, visiting https sites have secure connections but the site itself may still be for scammers, so this only handle the connection part no what is happening on the site.
5. Updating your device OS (operating system) and also updating apps. You can help prevent attackers from installing malware on your device by keeping your apps and operating systems up to date. Software updates often include security patches for recently discovered vulnerabilities
6. Visiting legit sites
7. Not clicking on ads and link ads
8. Making use of privacy browsers
9. Not making use of free VPN but paid ones that are also legit and have high quality reputations.
10. Making use of privacy search engine and many more that are addressed on this write up.

6. Keep your device always locked
Because of the differences between different operating systems and devices, we will only provide general recommendations here. Always set a password on your device. Biometric authentication, such as fingerprints should be sufficient for most users. However, people with elevated security concerns may opt to require a password every time.

When to use Tor
If your threat model requires a very high level of Internet privacy, you should connect to the Internet through Tor. Tor is a technology maintained by the nonprofit Tor Project, which allows you to use the Internet anonymously. It works by bouncing your connection through multiple layers of encryption, both protecting your data and concealing its origin. Tor also allows you to access blocked websites (such as those offering E2EE services) via the dark web. However, the downside of Tor is that it is generally significantly slower compared to using a VPN

Conclusion
There are lots of ways to have high privacy, but privacy can not be 100%, having knowledge about it can be effective in avoiding hackers. Hackers are threat to bitcoin and other cryptocurrencies, because these cryptocurrencies are digital based, we need to have high level of privacy to protect
them from scammers.
