...I have experienced the bitter side of Cryptocurrency and now I don't need someone to tell me that crypto can bite. Moving forward I would pay more attention to learning and asking questions too, all I can say to the newbies is that grow your brain before you try to grow your portfolio.
You could pay for training instead of paying for the experience you gained from unsuccessful trading and investing. It is possible that it would take you less time to acquire such an experience than it took for independent study. However, you have already figured out the source of your mistakes, and in the future you will have fewer disappointments that trading brings.
