At first, they ignored the Bitcoin, then ridiculed him for "how a digital coin does not have a physical presence" to be a substitute for paper currency and a system called the Blockchain, an alternative not only to the banks but to the entire institutions, then they fought him and tried to cast suspicion in the ranks of those who pursued him To 20 thousand dollars in less than ten years from the way he described the bubble and the closing of the trading platforms and then enter the market and try to control it as it is now.
Now only victory ...
You are right, a lot of people have ridicule bitcoins giving a number of reasons. It has proved all of them wring ad given more than 10000% returns in an year. I am sure that those people who were making fun of bitcoins must be regretting their decision now. They might be investing some money in bitcoins hoping to make some decent returns.
