Personally, I'm a fan of ecosystem/platform tokens. My portfolio is a mix of these assets with $BNB , $OKB and $BGB inclusive.
Considering BGB usecases, I've been more immersed in the Bitget ecosystem. The token brings forth passive earning opportunities via the PoolX and others.
The token is the 2nd largest CEX token, its price action since launch has been one to write home about, over 42K% from July, 2021. With its continued growth, the token is bag worthy gem and one to look out for in the nearest future.
