Yes, Bitcoin is controversial. But not only because it can be used to some illegal activities. But, it can also help a lot of good people who are having a hard time to earn money. There are just some people that are so against bitcoin,and maybe they were the ones who made bitcoin very controversial. It's okay, not all people are into bitcoin. There will be pros and cons. Especially now, bitcoin is rising up. And we have to expect that someone will try to bring bitcoin down
the current Bitcoin course is very strange, and first of all because there is a visible stop, after it has gone down from 20,000 dollars. It seems to me that his competitors, who are more promising than Bitcoin, will not let him rise. First of all, I would like to mention such a coin as the etherium.
