There's nothing to get afraid of anything. Rather than oanicking follow the procedure of hold and sell, you'd be able earn good amount of money.
When I was a newbie I was totally afraid in cryptocurrency, and there are some point that I panic sold and I lose 10-50% of my investments. I didn't stop in cryptocurrency world instead I study how the market works, I gain skills and improve myself in order to do not panic everything I see the market.
