I will recommend ethereum, bnb, litecoin, dash, Tron, maybe Cardano. I am not sure with kucoin, Huobi token, tezos, wanchain, but that coin can be potential too as the other altcoin. If you want to buy those coins, I hope you can analyze more by searching on many resources so you can find more information about each coin. But ethereum now already increases more than $200, so I think you need to wait for a while before you decide to buy ethereum.
