It seems to me that Binance is trying to monopolize the market and squeeze out its competitors. I dont really like this approach, but the platform offers many different opportunities and tools for trading, and not only that, so the BNB rate will always be kept at a certain level. So investing in BNB looks quite reasonable.
If you are looking for project that already have strong product BNB is one of those favorable investment to hold. Aiming for longer time frame it can
rally high and provide big profits to your investment, You can just let go with the swing and be positive waiting for much bigger blast.
Yes BNB is a strong player in the crypto market for the long term it will definitely be a good pick it has reached the ATH of around $40 from which it evolves to several new products like Binance Launchpad, Labs, Futures, Margin trading, Reduced supply through burns, in terms of adoption, Binance chain, etc FYI holding 30% of my portfolio in BNB.
Each of us has its own investment strategy, so to say that 30% of the crypto portfolio is a lot or a little is meaningless. I have several friends who keep all their savings in only one cryptocurrency and this is not bitcoin.
