Bitcoin and the Blockchain are not bad for the environment.Mankind’s incessant urge to burn fossil fuels is bad for the environment.If you want to mine in an environmentally-friendly way do so in a place where the electricity comes from green energy.Check out crypto projects like WePower and HydroMiner if you want to dive into green mining in a bigger way......!

A bitcoin ATM is an internet machine that allows a person to exchange bitcoins and cash. Some Bitcoin ATMs offer bi-directional functionality enabling both the purchase of Bitcoin as well as the redemption of Bitcoin for cash. In some cases, Bitcoin ATM providers require users to have an existing account to transact on the machine.

Bitcoin isn’t an object, it’s an encrypted address on the blockchain. What you own is a unique key that unlocks a specific bitcoin location, and that’s what you need to be protecting at all times by storing it in a wallet.The easier way to store your bitcoin and other cryptocurrency is in a digital wallet online, or locally on your smartphone or computer. But leaving your bitcoin in public view can open you up to attacks from hackers and phishing scams. That’s why the best option is a hardware wallet that stores your bitcoin offline.Most hardware wallets look like USB drives and can be easily connected to a computer. They use a PIN number for security, along with a secondary password called a “seed” in case you forget the PIN. If you forget both passwords you’re pretty much screwed, so it might be worth writing the seed down somewhere safe offline.

Bitcoin is the incentive to keep the Bitcoin blockchain secured. Without that incentive there would no longer be the trust factor, the network would have lost security.Imagine a centralized blockchain, where trust would be in hands of a few individuals or institutions. What if the private keys would be compromised? The entire network would have lost all value.Plus, trust centralized would be business as usual. It would be similar as the trust we are supposed to have in banks and authorities.
Bitcoin was designed to move away from the trust through institutions to trust through networks.

If you are on a personal connection, like at home, you can run an anti-virus scan on your device to make sure it is not infected with malware.If you are at an office or shared network, you can ask the network administrator to run a scan across the network looking for misconfigured or infected devices.Another way to prevent getting this page in the future is to use Privacy Pass.

It's a kind of tric from the side of banks. Because they realise that there is no way to protect banking system,so they forced to accept bitcoin  to cross border payments.

All of them admitted there's no perfect solution to the problem. In the age of cryptocurrency, hard drives and personal computers have become the new bank vaults. And our real-world knowledge of protecting money from theft is not enough in the virtual world. The following suggestions can serve as a safety pamphlet for new cryptocurrency investors.
1. Before you open up an account on Coinbase [or other exchanges], set up an unique email that you are going to use for that account.
2. Make sure to set a really hard and long password, and you are the only one to access it from a piece of paper that you control.

Fortunately, there are both short- and long-term countermeasures against network attacks. First, peer selections could be made routing-aware. Bitcoin nodes could, for example, aim at maximizing the diversity of the Internet paths seen by their connections to minimize the risk that an attacker can intercept all of them. Moreover, nodes could monitor the behavior of their connections to detect events like abrupt disconnections from multiple peers or unusual delays in block delivery. These events could serve as an early indicator of a routing attack and could, for instance, trigger the establishment of extra randomly-selected connections. Finally, solutions like end-to-end encryption would also help (especially against delay attacks). Yet, encryption alone would not be sufficient to protect against partitioning attacks as an attacker can still drop encrypted Bitcoin connections.

Bitcoin is always a big hope for us. So everyone always curiously looking for the drop to buy more bitcoins. Because bitcoin is always a hopeful investment in crypto market. Don't bother about bitcoin is current market desp.

Most of them buy altcoins too with bitcoin investment.Mostly, people get into altcoins as a way to hedge against Bitcoin. Here are some common reasons for someone to hedge with altcoins:
1,Bitcoin may have some catastrophic failing that the altcoin is not subject to.
2,An altcoin may have some future utility that is significantly better than Bitcoin allowing the altcoin to overtake Bitcoin.
3,Even if Bitcoin continues to be the most valuable cryptocurrency, there may be room for altcoins to serve some other niche and hence             may not be bad bets in their own right.

For the time being, all these governments around the world, are waiting and watching. They are trying to figure out what this new thing is and how far it can go. As fiat currencies devalue more and Bitcoin goes up, they will be forced to make decisions. Some may make policies to regulate them while others might declare them illegal. But there’s no stopping when it comes to technologies like the internet or smartphones. And make no mistake, the Blockchain based industry is going to be as big as these two, may be even bigger.So, the governments and leaders around the world can bite off all they want, but chewing would not be much of an option.

Its realy a good news. Im sure they will accept it, they don't have any option because in future bitcoin is the main crypto that going ti accept all over the world so on that time accepting bitcoin as a payment  will be a great privileges for them.

We cant predict an exact result in case of this but from my experience  i think bitcoin will always  be the mist dominant coin because there is no other coin have the power to maintain all issues that related to cryptosystem.  But in case of bitcoin they can beat with their experience level in this field.

It's the best time to make more purchase of bitcoin . It's a great opportunity to all new comers and those who are left their dream of buying bitcoin because of lack of money. So don't be waste time and utilise your opportunity.

I'm not sure but I can say that the most probable crypto that will become the first world currency to buy and sell is bitcoin. Because if you take a survey of number if each and every crypto users then you can understand that bitcoin is the top one in consumption.

For what purpose the government make illegal bitcoin? ,there is no use if they use bitcoin for illegal. They are missing tax return from it through illegal use. They can earn more from implementing tax from it than illegal use of bitcoin.
