You can of course wait, and Bitcoin will arrive at this price again on a certain day.
But you can still sell them now and buy them back at a lower price to avoid more losses, this is also a trading method.
If you believe this technology should not be so concerned about the price, just hold your coins.
Obviously, you don't really believe this technology because you are afraid.
You are wrong, i am not afraid ... it's my reaction when saying panic sell, or when i see peoples afraid because they lost their believe on this technology.
And at the end, they start criticism and spread a bad word about Bitcoin because they are weak !
That's good, I am not afraid, so I will not care about any FUD about crypto, and I will not advise anyone to sell them. In my opinion, I only need to stick to my own ideas, and the rest worry is superfluous.
