First of all, you do not need to panic. Now almost all the holders of the crypto currency are in about the same position, as the crypto-currency market has completely fallen in price. The coins you specified are quite promising, so there is nothing to worry about. We just need to relax and expect the rise of the crypto-currency market. Over the past seven years, the first half of the year in five cases has always been not entirely successful for the crypto currency. Therefore, such a general decrease in prices should be perceived as the usual state of the crypto currency, which always ends with its rise.
