Lovely initiative, good for you!
Two suggestions from me:
1. Edit your post with the addresses. I, for example, don't use QR codes on a desktop.
2. Add Tether (USDT) TRC-20, Neutrino (USDN) & Tron (TRX) wallets because they have zero or close to zero fees.
Good luck!
that's a good suggestion. Will add the text addresses now.
