Do not say it is stupid, investing in Bitcoin is no different than investing in gold or dollars or playing securities. However, the electronic money market in general and Bitcoin, in particular, is a new investment trend and of course, if you pick up the trend then the opportunity to make money is always wider when it is saturated as evidence. There is a huge potential risk, of course, of any market so high profits are always accompanied by high risk, you should determine this from the beginning. Currently, I have sold the bitcoin clean and had the profit that bitcoin brings.
