Patience is really a virtue. We always learn from our mistakes. If you had sold it for that amount for reasons of badly needing it that time then that's alright. It had helped you that time. If you have no other resources other than your investment then its somehow a right decision. That's why before engaging in this kind of investment, we need to have an emergency fund to sustain our daily needs. Otherwise, you'll have no other choice but to get it from your investment.
This is why I like to encrypt money. We can learn from it that if we can solve the problem, we may as well wait for calm and anxiety. In many cases, we will always be anxious about something. We will do nothing for this matter. However, In fact, it is irrational. Relax yourself, stick to your beliefs and we all believe in cryptocurrencies.
