We can estimate the energy consumption, based on the complexity of bitcoin. Complexity is the value calculated by the protocol and attached to each block. Complexity measures the average number of hashes left by the miner to search for one real block.

When discussing the market, crypto currency is very often paid attention to its high volatility. Is volatile crypto currency an unavoidable problem for everyone who wants to invest in crypto-currencies? Or is not it all so scary? I think that dollar is also volatile but it is used as the main currency.

In recent years, Bitcoin's influence has led to changes in various industries. People started to accept Bitcoin as payment, these are mainly companies that work on the Internet. I think this means that soon it will get legitimacy

Today, many central banks are closely following Bitcoin's development. Some of them even proposed a digital version of their currency. For example, the central banks of Canada and Ecuador are among the first to study such opportunities.

People store their bitcoins in a digital wallet, which, for example, is in the form of an application on the phone or in a computer. The system is reliable, but you can always catch such a computer virus that will steal your password

Since the appearance and popularization of bitcoins, a number of forks, that is, derived systems, have emerged. This is facilitated by the availability of open source code, making crypto currency more popular in world markets, especially shadow markets. I am sure it will rise soon!

In comparison with conventional money, they do not have a single issuing center or course management body, their lists, status. Everything is built exclusively on the complex process of creating each new unit of virtual money, its use to buy or sell anything. Distinguish electronic money by methods of payment. The initial value of the crypto currency is determined by the "Proof-of-work" approach, that is, the evidence of the work done to create it.

The recent criticism of the bitcoin network is that the increase in the commission fee for the transaction made it unusable as a payment system. Nevertheless, in reality, the growth of fees is healthy and expected. I think it will recover soon!

The finance ministers and heads of central banks of the 20 countries prepared a draft regulatory document that states that the crypto currency "does not have any signs of sovereign currencies" and should be regarded as an asset

Some experts predict the collapse of bitcoin. Others assume that when the maximum emission is reached, the rate of the Crypto currency will begin to change approximately the same as the real ones - to move up and down under the influence of various factors. Therefore, do not make hasty conclusions about whether it is worth buying bitcoins in 2018. It is best to weigh all the pros and cons first.

Investors are still waiting for some important event to buy a coin with a long-term prospect of profit, according to Newsbtc analysts. In their opinion, the serious recession that occurred with the digital money market in early 2018 is due to the correction of the majority's rate, as their value has risen too sharply in late December 2017 and early January 2018.

I have heard about the idea to build the mining-city. It will help the Russians to earn and replenish the state budget, "If we build such a settlement near the border, for example, with China, it will immediately arouse great interest, there will be flows of business tourists. Such a place will become a business forum, will bring investment from abroad"

First when I saw your post I thought Why did you post such information) but then I understood your sarcasm. Thanks, it was really interesting to read it and I think that it was very useful for many of traders. Scams are everywhere today and we need to know how not to face it

I don't agree with you because the price of BTC will definitely rise as there are  many people who still want it more than anything else, including me. I have read a lot of expert opinions on its future and it will reach great heights!

I can recommend you to buy either BTC or Ether because they both are known as the most wanted coins with good future prospects. I think that it is necessary to invest in one of them, though btc looks more advantageous for me personally

I think that risks are everywhere but when investing in the real estate you take less risks than in any other business. The price of the real estate may be not stable as there are many factors it depends on. However, as for me, it is the best decision

Why not now? In my opinion, traders know how to trade even when there are fluctuations, which don't prevent them from earning good profit. I don't know how they do this but this is a fact that some earn even more on volatility

I m not great mathematician but I agree with the last post where the person calculated the profit 4$, seems not much. I think that you need to reconsider the strategy you used as it doesn't work well and you will not earn much

I don't know as I give preference to bitcoin only. It is worth it! I like that it is based on the blockchain technology. I consider it the best one for trading and holding. Now I like holding strategy and think that I will win in the future

Yes, today, there are really too many crypto currencies but I am sure that this is not necessary to choose any of them, except btc and maybe ether as well . Both are popular and most wanted. I think that others aren't very safe
