Crypto is now an ecosystem and digital money for investment and transactions. Everyone comes with an investment goal and makes a profit and that is indeed the reality. Only a few are truly investing in future projects and that is a truly wealthy person. There is nothing wrong if people come to get rich, but the thing to remember is that a crypto is a place full of risk without collateral
Probably OP had never made good in investing cryptocurrency because of having losses. Losses is part of investment whatever investment you may had. I agree with you that cryptocurrency is one a high risk form of investment and this could mean also that there is a high chance on getting high gains or the opposite which will be getting more losses. It is up to you when will you going to buy crypto, risk your money and decide when to sell crypto. Trading is very common to others who enthusiast with but most likely the best thing to gain here is risking money to buy crypto while having market crash and then sell it whenever you want after the market made a recovery but never buy again unless it will be having a market crash for crypto again.
