Just move on and learn from your mistake dude...if you keep on blaming yourself for that loss or you are stuck in loop thoughts of regret, that is not going to get your money back!
Yes, it is always good to move on because if you stay it can't make you learn. So you have to move from your mistake to profit-making steps.
In this industry, we have to move on, if you stuck at one point and you can't regain back all your knowledge.
Why I could not? If I accept my loss and use the remaining amount for try invest to other coins, I still have opportunity for regain my money in someday.
