I am only familiar with ADA, ZIL, and COTI. Based on your portfolio, I would suggest higher percentage in ADA. I will also suggest investing with cryptos having huge names because those are the ones which are having a bigger tendency to recover especially at this moment wherein the market is filled with red marks. Selling some of your crypto holdings should depend on your market analysis because it is you who will earn from your investments, and likewise in order to avoid regrets from depending too much with other's opinion. You may use the recommendations as a guide but do not allow those things to dictate your actions.
