No one can help you but you. Losses are losses, and it's irreversible, but you can take back what you have lost by making good in your trade next time. Trading requires patience. You need to watch closely over your trade, otherwise you will really lose all in just a blink of an eye. Instead of crying over that milk, invest in more stable coin. You can do scalping so that you can recover what you have lost. Small profit, yes, but somehow it will accumulate and get big.
