Yes my friend has become very rich thanks to bitcoin he cashed them out when they were 7.5k and he bought them for 950 dollars at the start of this year so he had a lot of profit because of the pump and because of this great year of crypto currency.
Imagine that there was a guy that bought some coin when he was doing a "work" for studies and after years he found out that he has thousands of dollars on account!
Yeah bitcoin has proved on thing that this coin changes its investors lives in short time and there are a lot of people who are mediocre when they invested into this coin and now they are enjoying their lives in epic way and all this is just because of bitcoin and it delivered what it promises so those who are willing to join them they must have to grab btc and hold it for suitable time and they will become rich like them.
