I won't sell if I was caught with a big loss. I'll just wait for the price to go back to its normal price. I'm certain that this won't be long. It's just the normal and initial reaction of altcoins to the drastic surge of BTC. But since they are correlationally proportional, green days for altcoins will come as well once the correction is over. I don't wanna lose even bigger for being impatient.
