There is not much advise you can get that will specifically address whether or not you should sell the cryptos you currently hold in your portfolio.The major reason is because one can not tell the price at which you bought and what your intentions are as regard each purchase.You may have bought to hodl for a long time or to day trade (not very good in current market trend).I would suggest you hodl or be patient for a while especially if you bought at high price.I have a feeling the market will soon recover.There are some indications to that.Also,do not take every suggestion anyone offers you without doing some personal research or findings.I hope i was helpful.Regards.
