Current mining cost of BTC

1. It's hard to say. Anyway, lightcoin mining is basically no longer profitable, so is bitcoin. Some time ago, e to the sharp drop in the price of lightcoin, Zeus lightcoin cloud mining project has stopped mining. The mining of Laite coin is still so, and the mining of indivial investors is even more difficult. There are different opinions about the cost of bitcoin mining, some say 1500, some say 500. This has something to do with the performance and electricity price of the mining machine.

2. At present, the most popular way of bitcoin trading is contract trading. According to the rise and fall of the price, it is far better to obtain income than the traditional mining and direct trading. After all, there is no need to really hold virtual currency, just need to judge whether the price is up or down, which is very suitable for the existing investors, simple and convenient

4. Mining now? The cost of bitcoin is too high! Now that the situation is over, you might as well know about the Khan currency, which is a real virtual digital cryptocurrency. Now the price is only a few cents, which is very cost-effective. You can know about it

5. Bitcoin mining machine can be done for tens of thousands of yuan now, but the high electricity cost is not affordable by most of us. It is not recommended that bitcoin can choose some other currencies for mining.

6. Get out of the way. I'll answer
literally, bitcoin comes first, then blockchain. Bitcoin started in 2009 and blockchain started in early 2014
in essence, blockchain technology is a collection of technologies, mainly composed of distributed account book data
bitcoin is an application. In order to achieve some of the purposes of bitcoin, some technologies are used, because bitcoin is more and more valued by the market (that is, the price is getting higher and higher). These underlying technologies are later refined and called blockchain separately

then, their relationship is similar to that between internal combustion engine and automobile
in order to run, cars use internal combustion engine technology
the internal combustion engine technology is also widely used in trains, small power stations, agricultural machinery, engineering machinery, merchant ships, conventional submarines and small airplanes because of the wide application of automobiles. The number of internal combustion engines in the world ranks first among the power machinery of human beings

if you understand the relationship between blockchain and bitcoin in this way, is blockchain technology important
it's important, but more important is the structure of all kinds of human data and the decentralized future realized by this technology.

7. First of all, it depends on the background of the company. Then it depends on the company. Where is the server and what is the mode? Violation of the law or not, if there is no problem with these, you can invest!

8. From the traditional promotion is divided into offline way, mainly about the promotion in the entity and the Internet is divided into different ways.

The mode is always changeable, but it's always the same, no matter which promotion channels are only for a common goal: profit
the above is purely personal.
