I would have been easier for all if you just decide to share your tips here on the forum, from my previous knowledge, if one does not moderate a Discord server tightly, it is just matter of time before scammers start coming and try to take advantage of the members.
It is something that unfortunately happen in many crypto-related servers.

Still, good luck with your server. I personally think tips are supposed to be free of charge.

Anyone considering to join, beware of scammers, do not share your seeds with anyone on Discord and do not send money to anyone directly.
