If you lose $2,000 worth of cryptocurrency, then there is a problem to you. Check first yourself if you have capability in trading because if you will continue what will you do, it may lead to total bankruptcy. Unless, you are a millionaire.
Trading is a risky way of earning, you may gain or lose money. If you will enter the world of trading, be wisely and knows every side wether dump or pump of the coins you hold.
I agree that there might be a problem, but I wouldn't say that it would automatically be the person who is investing. I mean, there are so many other factors that could affect an investment and make it go down the drain, therefore, it would be better when losses like that happen to actually take a step back and look at things with a fresh eye and see what went wrong. If there are things that can be changed, then it should be addressed; however, if what happened was related to normal market movements, then another strategy should be employed.
