You didnt follow the most important rule for investments in crypto: buy low, sell high.

But joke aside, I guess there is nothing to worry about, crypto is a heavy volatile market and there will always be dips, corrections and even crashes. But as we are still in the infancy of cryptocurrencies, it pretty much certain that your loss will recover and you will end up in profit. Just dont panic and hodl. This strategy has payed out for pretty good so far.
