In my opinion, we believe in cryptocurrency because it is already proven as a great digital investment. Many people around the world have proven it and take big advantage of crypto. Why not follow them and try our luck in crypto investment as well? However, we need to have sufficient knowledge if we want to invest in crypto. Investing or trading in crypto has a big risk as it has big volatility and instability in price. If we don't know how to deal with these characteristics, we instead risk our money in crypto investment. But there are many sources to get knowledge about crypto investment lately, so don't worry!!
