I allready updated my Wallet, and got a 2xxx adress
i wanna know is that a problem for you and the campaign members
to receive btx, because we dont know if you use old or new wallet

Thanks in advance
Should not be an issue at all. They can easily convert from one to the other. Old wallets can send to new no issue. Just have to convert the address first. Depending on the situation.
