Wallet vs Storage for powerup's

Hi i want to know which nakama feature is best to save number of purcased/remaining powerups of user.
wallet or storage ?

Hello @KGS.

Which is best depends on your requirements, but I think the Wallet APIs have some niceties that the storage engine does not provide as it’s geared towards handling currencies - for example, it disallows to subtract more funds than what are available.
