Firstly eth, which will be number one altcoin in 2021.apart from that, bnb also doing well.binance exchange try best to promoting them & gaining traders who'll help bnb to raise more.even i can see lots of potentiality in polka dot, for upcoming future.so polkadot will be one of the best altcoin, i believe so.even project are launching though tron, which will also be a good altcoin in 2021
of some of the coins that you mentioned the current situation is experiencing a fairly drastic downturn, I can also see the progress of some coins it looks good but if not supported by market conditions some coins it is hard to up only a bull run could make coin it go up
