Security continues to be a high priority for software developers. The latest developer to make sure its services offer users maximum protection is Viber. The popular Viber app is now set to incorporate a brand new feature which will be implemented to the existing Secret Messages feature.

Will your application have video or audio calls?

Maybe you're right, but in any case, do not forget about privacy

China is big.  In fact the bitcoin community in China is a small and very minor part of fintech.  However, with a billion people.Most mining pools are actually in China, which mean miners first sell their BTC to yuan and since the Central Bank of China doesn't control the Bitcoin, is a good business.

There are a number of ways to do this, nearly all of which are to a certain degree convoluted.Personally I prefer to transfer them to a debit card and then I can use that to spend or withdraw as normal.There are a bunch of bitcoin debit cards around and they all serve much the same function but remember you are still paying with a Fiat Currency such as EUR, GBP or USD.There are a number of prepaid debit cards that can receive bitcoin as a top-up method but they are converted to the Fiat currency for use with the card.

I use tor, because My ISP forcing me to use it by blocking some of the websites and won’t give explanation on why they are blocked. In bangalore, my ISP is tikona and they blocked

In the UK, if the cryptocurrency has gained in capital value since you acquired it, you pay capital gains tax. To be liable for income tax on the cryptocurrency, you need to have had the cryptocurrency paid to you as income.

Switzerland is adopting legalization through local government fees, an example is the municipality of zug and chiasso, where it is possible to pay taxes in bitcoin.As far as companies are concerned, the activity is totally legal but in some cases falls under the supervision of the Swiss Financial Market Supervisory Authority .

China hasnt banned it.There are  will probably regulate and back their best companies, making giant monopolies of a very small groups.

Wellll, I've heard somewhere that  Russia can legalize bitcoin and other crypto-currencies as early as next year. The Bank of Russia and profile departments now determine what status they should get. At any given time, the state must know who is on both sides of the financial chain. If there is a transaction, the people who conduct it must understand who they are buying from and to whom they are selling, just like with banking transactions

The Bank of Russia and the relevant departments are developing a joint position regarding the status of the crypto currency. According to him, afterwards, approaches to their regulation will be determined.

Fees are high because transaction capacity has become an artificially scarce resource. There’s only 1MB of data allowed per Bitcoin block, or in other words, only 1 MB of data allowed every 10 minutes. It’s a piddling amount of data, considering that my home internet connection has a download speed that’s 420,000% greater. It’s important to realize that transaction capacity is currently scarce because of a limit that was placed into the code and that has been kept there intentionally by the Bitcoin Core developers.

Without this artificial limit, there could still theoretically be a scarcity for transaction space, but it would be purely market driven (based on the willingness of miners to produce bigger blocks.). As it is now, this artificial constraint of 1MB means that you have compete with everyone else and simply outbid the rest of the world.

Sucks, right?

While determining how “good” any investment will be is ultimately a guessing game, there are some tried and true ways to determine an asset’s worth. One of the simplest ways to think about bitcoin as an investment is to consider its rise against the U.S. dollar. Recently, bitcoin prices eclipsed $8,000 and have reached beyond $10,000. If you had invested in the digital currency when its worth was still hovering around $800 just a few years ago, or when it was first introduced in 2009 and worth nothing against the dollar, you would probably be convinced that it made for a good investment.

Furthermore, an underpinning concept behind Bitcoin is that there will only ever be 21,000,000 tokens, meaning that it may stay consistently valuable or increase in value relative to other types of currency which can be printed endlessly. Other reasons that the asset seems like a good investment include its growing popularity, network effects, security, immutability and status as the first ever in a growing world of digital currencies.

It should go without saying that you should treat bitcoins like the money in your bank account. Cryptocurrencies become more popular day-by-day, and thieves have definitely been paying attention. In the last five years, over $500 million of bitcoins have been stolen.

How is this done? For starters, 22% of all financial malware attacks target bitcoins. Over 12 exchanges (including Mt. Gox) have been hacked and there are more than 140 viruses out there that target bitcoins as well. On the upside, these threats also present new market opportunities for cryptocurrency related protection services.

Famous venture capitalist and Bitcoin proponent, Fred Wilson, believes that digital currencies will have to be more secure to gain mainstream adoption. This means exchanges and wallets are going to have to be better. Entrepreneurs around the world are trying to figure this out right now, and many of their new services could – in the process – also disrupt the financial system as we know it.

I doubt that there is any other cryptocurrency or altcoin that can supersede the bitcoin. At least not for the next 5-10 years. Of course there are many rising competitors like ripple and litecoin. The newest addition to the list of its competitors is Ethereum. Ethereum has launched its own cryptocurrency called Ether that showed an exceptional growth last year making it the 2nd most popular cryptocurrency of 2016. And for all one knows, Ether is the only currency right now that owns a slight possibility to outpass the bitcoin in coming years. The biggest accomplishment of Ethereum perhaps is the support from some leading organizations like Microsoft and IBM. Microsoft’s US based financial team is now working with Ethereum to offer blockchain as a service to various business firms and financial institutions.

Although, we must not forget that it’s been just a few years since the bitcoin came into existence and there’s still a long way to go. And as the time goes by, we are going to witness many other astounding aspects of this virtual currency.

The price will go up and down as it does today. but probably it will be less volatile. price for 1 btc will be not less than 20k.

However, it's also possible that more governments will ban it. but I hope crypto will become a mass adoption in the end. but you never know. we will see. anyway, I'm excited about the future of crypto.  If they are worried about their own economy and have some common sense they will not do that. In those countries where bitcoin has been declared illegal are those with small economy and are poor compared to other countries. Moreover you can always use anonymous services to help yourself stay anon and not be detected by the agencies if you decide to use BTC while it is banned.

Well, no one canbe 100% sure about its future. We'll wait and see.

The interest in cryptocurrencies evolved immensely and today, more and more players are seeing it as a new investment option We are now at a stage where the interest has evolved from the early adopters to including institutional and retail investors. This adoption represents another turning point for digital currencies and an impressive shift when you think of how just a couple of years ago Cryptocurrencies were mostly used for black market transactions.

The other point is that digital currencies, especially Bitcoin have made a lot of progress to become a safer and more secure environment. Advanced forms of encryption and bespoke algorithms are only some of the ways these digital currencies are trying to provide the safest experience to their client. This progress has made more investors inclined to “trust” these platforms therefore increasing the demand for cryptocurrencies.

Governments do not want to see competing currencies. They threaten their monopoly to create money and control the financial system and the economy.

Actually, the reason China is the first big government to take such action isn’t an accident. China more than any other country wants to have firm control of its banking system, and allocate credit according to a political agenda. This means that a competing currency like the Bitcoin would threaten its political system. Why not crush it sooner than later?

While it is still unclear whether the Chinese government will achieve its real objectives, one thing is clear: the buzz for the digital currencies is gone, at least for now.

Hackers can crack wallets through the vulnerabilities of cellular networks.

Experts have established that bitcoin-wallet can be hacked through vulnerabilities, which are currently available in cellular networks. This is a vulnerability in the networks SS7. During the experiment, specialists managed to get access to a pre-created bitcoin-wallet in Coinbase. To date, this exchange is used by about 9 million people.

Using the detected vulnerability, experts managed to intercept SMS messages through which users are sent passwords for one-time use. After that, the user's email address was determined, through which you can access the funds stored on your wallet.

However, at present, mobile operators are working closely with a group of consulting companies in the field of security of telecommunications systems and protection against burglaries, including electronic bitcoins, for storing crypto-currencies.

First of all, If we talk about the shortcomings of bitcoins, then this is a large volatility of the currency. In other words, even a month the price of bitcoin can make huge leaps. What is more, Bitcoins are still only accepted by a very small group of online merchants. This makes it unfeasible to completely rely on Bitcoins as a currency.

The most terrible dream for a person using Bitcoin will be the loss of a wallet.  If a hard drive crashes, or a virus corrupts data , and the wallet file is corrupted, Bitcoins have essentially been “lost”. There is nothing that can done to recover it. These coins will be forever orphaned in the system. This can bankrupt a wealthy Bitcoin investor within seconds with no way form of recovery. The coins the investor owned will also be permanently orphaned.

And, finally, Bitcoin has the signs of a financial pyramid with all its inherent properties: attractiveness of quick profit, high incomes of the first participants, extremely high difficulty in obtaining monetary units for new members of the system, etc.

Cold storage is the process of storing your Bitcoins offline. This is the safest way to store Bitcoins, especially when it comes to a large number of coins.

There are several methods of cold storage:
1- paper wallets
2- USB storage devices or other forms of standalone storage media
3- offline hardware wallets
4- Fragmented secret keys

Although cold storage is undoubtedly the safest way to store your Bitcoins offline, it all depends on the safe storage of files or private keys that, if lost, will disrupt access to your coins. In addition, using a wallet on the desktop can be quite difficult for non-professional users, so carefully follow the instructions and use more than one place to store your files

How to create a cold wallet storage you can find out by yourself. Now, there are a lot of useful step-by-step instructions that will help you.
