If you follow the principles you are bound to get reward. That's what I did. bought $SOL at a support price and held it for some time . and now am in profit. $SOL is a promising coin and its current price is very under value. three years from now you see what it is.
however crypto market is very volatile and prone to high value swings. greed is curse as wise men said. my advice is not to deal in future trading . only trade in spot so that your assets are safe. never forget to use stop loss. it's better to lose lesser amount than large sums.
summary :
1. Follow the principles
2. don't fall for greed
