Everyone know Bitcoin is up to 50000 CNY. It is terrible. I admit Bitcoin is the first digital currency and it is more important than others. But after BCC,BTG were folked i do not think so. And is it fast, the answer is obvious. So technically it is not a good currency. Why people have belief on it? The price is from 16000 to 50000 in two months, it is just up,up and up. So what do u think about it?
