Your mentioned altcoin are best i think. But some problems in ripple (xrp). Anyone can invest on eth or bnb. Both altcoin is best for investment. ETH is second position on cryptocurrency market. Huge volume and huge people investing on ETH. Also eth chain is very popular. Next BNB also very good altcoin. Day by day bnb chain being popular. And usability are increasing day by day. Because BNB is a products of Binance. Ao its future very bright.
