Yes, cryptocurrency can be life-changing, but one must be making the right choices and learn the many big mistakes by others, and that others include me. I started back in 2017 and BTC was not, yet a big thing back then, it was still struggling and although at the last quarter of the year there was a big bull run the following year the whole crypto industry experience the winter. In 2018, I sold my small BTC for personal reasons (the rate was just around $3K+). I made good bounties in 2017 yet my mind at that time I was thinking that growth will not stop until we then experienced the winter where values of many coins and tokens lost 80-90% of their original value. Then just last year I made a another stupid decision of converting the BTC I got from bounties into another coin which was then rising at that time but months later the value of the coin crashed to the ground. Many mistakes, many lost opportunities.
