Bitcoin is the best as a crypto asset. This year there will be a lot of competition going on especially on the top coins. BNB will remain Ethereum's main competitor. Then there is Polygon which continues to show good performance and this year I think I prefer Polygon (MATIC) over Binance Coin (BNB) and Ethereum.
We'll find out when the year will end, if the market will be bullish, there's no need to choose as all coins with great development will eventually rise. Ethereum and BNB are the top altcoins, they'll lead the altcoins season but of course MATIC might also follow the same trend as it also have a decent volume and traded in Binance.
Binance is more focused on Exchange and BSC. While Ethereum is still in the midst of tackling gas costs. Of the two things, I think Polygon will be superior even though we admit that BNB and ETH are the top altcoins.
