I think mina wallet creation fee need to be reduced, now not so important but if prize goes up will be a problem.
About deactivating accounts, maybe could be a solution to recover the fee, but seems hard to code and in future could be a expensive recovery for the network.
I think it’s better to change the fee as prize moves, is it possible to make the fee fixed to a stable coin cost? Like 2 busd and convert to realtime mina cost in the creation of the wallet moment?
