My former colleague bought 100 bitcoins for 100000 yuan(RMB). At that time when he was not allowed to "sell and buy" in China, he was a little flustered and wanted to sell. After tossing about for a long time, only more than 50 pieces were lost. After calculation, about 40000 pieces were lost, which made my colleagues very depressed. When he was angry, he didn't give out the remaining 50 bitcoins, because he thought at that time that he had already lost, so he would keep the 50 bitcoins as a souvenir.

I didn't expect that later, bitcoin could still be "traded", and then bitcoin began to soar. At that time, my colleagues looked at the rising bitcoin every day and regretted that they should not give out the 50 bitcoins.

But recently, a bitcoin has broken through 60000 US dollars, and my colleagues are open to it. Because of the 50 bitcoins in his hand, he has more than 20 million wealth. Moreover, my colleagues are very optimistic about the future of bitcoin, saying that it will definitely break through 100000 US dollars this year. Ten years from now, it's over $1 million.

Anyway, my colleagues said that he won't lose one now. Many people around me play bitcoin, but he is the only one who can make money. Because most people don't have it. My colleague was also lucky. At that time, he didn't have the brain to give out all the coins.
