Just a single reliable mint will do me at this point
you should decide on your own which custodian you want to trust or deem reliable. Cashu devs can't give you any recommendations in this regard. We're working on better ways for mints to advertise themselves so it will become easier to disvover mints. In the meantime please be aware that cashu is still in early development and should not yet be considered reliable don't be too reckless :)
