Exchange coins that bring dividends (kucoin shares, binance coin, cryptopia shares, coss) should not fall as much as the rest in theory, those are things you want to hold. But with the dividends losing value their price will still drop. Then, you have to look for some coins that have been purchased in fiat as much as possible, now and in the past. Tether has inflated bitcoin and possibly ETH prices; if people got the coin without going through those it shouldn't crash.
