dont know fuck all about XRP but cant u just send 1 XRP to each wallet then they over the minimum!?
In order for a wallet to be active on the ledger it needs to hold an amount of 20XRP+.
A balance below 20XRP means the wallet cannot he used whilst a balance of 21XRP would allow you to love the 1XRP but not the 20.
The way for you to be able to access some of the funds in the wallet is if the reserve amount is lowered.
