I totally agree with you, investing in crypto has a very high risk, however we must be able to deal with that risk, if we are smart to do research and analyze coin movements we will most likely avoid losses, I think investing in crypto doesn't have to have large capital we can choose 1 or 2 altcoins that have potential such as ethereum and binance, these two altcoins have very active movements in the market, therefore we must be careful in determining when to buy and sell them.
