this is the cryptocurrency market, don't think that you will always win, also think about losing and do not invest money that you need

I don't know what's happening with these coins. I bought it at 1.2, it fell to 0.7, I took almost 8 days waiting for it to rise so I wouldn't sell at a loss, I just sold 6 hours ago at 0.7 with a loss, and now it's going up. What is this nonsense?
