Last month, I had dinner with a friend, and he said he was playing with something called Bitcoin. I can't remember the English name, BCT or BTC. Do you know what Bitcoin is? He said many hackers use this thing to pay. Now the price of this thing is almost $1. Should I buy a $1,000 one to keep? Give me some advice! ! $BTC #灰度撤回以太坊期货etf申请 #BTC走势分析 #Meme币你看好哪一个？
