Exchange tokens over wallet tokens any day! My fellow forum member TastyChillySauce00 has already mentioned the benefits of holding an exchange tokens. They are well established in the market and backed by a value generating business. So the chances of price increase is much higher in an exchange token.
Wallet tokens can become a good alternative though. I am not against it. At least a wallet tokens is obviously better than a memecoin.
I also consider a token's utility before investing. One with multiple utilities is my go to. From my research, I found that BWB will be used as the governance token for the wallet, can be staked for more yields and paying gas fees across multiple chains with the future release of the Account Abstraction (AA) wallet among other utilities. I think having both BGB & BWB is a plus. I am considering staking BGB in the launchpad to acquire some BWB
