I think for now the most valuable coin is BNB, because I think BNB is very good, it can even compete with ETH, BNB has a gas fee that is much cheaper than ETH. BNB can continue to grow, thus becoming an important part of the crypto world
As Binance provides good or excellent service, it's no doubt that BNB can still have a lot of future ahead especially if they keep the exchange top. It's also applicable in other altcoins that provide service that is usually used by crypto hunters or traders as they can use it or also invest in it as we also used it. Hopefully, there will be more legit altcoins that will provide a good program in the long term since there are plenty of altcoins from ICO before that lose their value now.
