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.
Don't ever put all im crypto, putting allowance or property in crypto were not a good idea since we can't guarantees in growth, but as time passed by we all know if we invesyed on right coin and it's developed it will punp so just wait.
