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
The great part that people miss is the fact that they are always hip with whatever is going on. When they first started, they started with BNB and allowed people to trade cheaper with BNB, creating a demand for it, they started with affiliate so you can invite people and be basically partners with them on the profits made. Then IEO became more famous, so they did that, people liked it and used that, billions were made that way. Then DEX became a thing and they started their own, listed many defi projects, then DeFi became a thing and they promoted their BSC and now we are at that stage, they are making money from that part.
Tomorrow there will be something else that is famous which all crypto market uses, and they will get into that, and they are never late neither, they have amazing developers who build things very quickly. So BNB will always worth a lot, no matter which direction crypto community goes.
