users can buy bitcoin, at the same time, they can also use the computer to "mine" bitcoin according to the algorithm. When users "mine" bitcoin, they need to use the computer to search for 64 bit numbers, and then compete with other gold miners by repeatedly solving puzzles to provide the required numbers for the bitcoin network. If the user's computer successfully creates a set of numbers, then they will get 25 bitcoins
e to the decentralized programming adopted by the bitcoin system, only 25 bitcoins can be obtained every 10 minutes, and by 2140, the maximum number of bitcoins in circulation will reach 21 million.

as we all know, the currency market in 2018 was a tragic year. At the beginning of 2018, the price of bitcoin was at the highest level in history, and the concept of blockchain began to heat up. A lot of people who originally belonged to the outside circle swarmed in to participate in entrepreneurship, employment and money buying. The prospect of the currency market seemed to be very good. Later, as we all know, as the price of currency fell again and again, the newly established blockchain media fell down one by one, and those new people who followed suit to buy currency were trapped in a high position to discuss; Bitcoin& ldquo; Blockchain & quot; There's less and less sound in the room. The coin ring gives these new comers a sense of cruelty
More than 90% of the people are trapped here, and faith is a very strange thing; Like the queen in the last kingdom of American TV series, the Danes gather to attack, she still says & mdash& mdash; God will punish the infidels and calm downlast year, all digital currencies and ICO platforms were shut down in China, and all countries in the world have put restrictions on them. At this time, few ordinary holders are willing to sell, and they basically hold them. This requires great determination, life problems, currency speculation problems, all kinds of problems may cause no longer hold; These problems cause a lot of trouble, so many people do not live well. After half a year, the instry that countries all over the world have entered is & lt; Blockchain & quot; And digital currency! In the game of blockchain, many countries have made some moves, and the holders are also on the sidelines

I think what you're talking about is that bitcoin is often hung up on the Internet, which I know is divided into different levels. The higher the level, the higher the income and investment. But I feel like it's a hoax. This thing has nothing to do with bitcoin. Their promotion model is suspected of MLM. They told me they were mining, using thousands of computers across the country. If you are in the mixed currency circle, you will understand that ordinary computers can't find bitcoin now, let alone thousands, even tens of thousands of ordinary computers can't find a bitcoin a year. In addition to wasting electricity, there is no profit at all. How can I give you money without profit. Now there are thousands of professional mining machines, which can dig a coin a day. Now the cost of mining is basically higher than the cost. Of course, the electricity charge is free. Now the world's well-known mines have stopped mining because of the sharp drop in currency price
this scam is not very clever, but I don't know why so many people believe it. Of course, some people tell me that I can make a lot of money every day. I want to say that if there is no sweetness, will you do it, will you pull the head, and will you invest more? Some time ago, bitcoin house reported a MLM coin. An aunt was dazzled by huge profits and was cheated by more than 20000 people.
