While BNB appeals to the wider crypto users because the binance smartchain currently seem to have overcome the biggest issue that most cryptocurrency users have with bitcoin ethereum and the ERC 20 blockchain tokens. This problem is the speed of transaction and and the cost of transactions.
This is a problem that BSC currently solves, and while a lot of people might argue that BNB is not a fully decentralized coin, i think it is worth noting that a lot of users dont care much for how decentralized a coin or token is, they just want the solutions they it offers.
This is why i think BNB an the BSC will remain very valuable in years to come
That totally depends on the market and the project owner as well. If the developers will keep their promises to the investors, that we can expect the value of BNB will still be growing. And as long as the crypto market is still active and growing, definitely there is a big chance for that.
We don't have a 100% assurance for this but seem to be looking positive base on what we have seen this time and since its launching.
