No, RaiBlocks does not need confirmations, but we do, due to the nature of XRB we wait for a certain amount of blocks before crediting to ensure the forks are all resolved an no rollbacks occur.
We also have to move it from the user accounts to the exchange account so user can withdraw, so this gives us plenty of time to do that and intercept, prevent any issues that come with instant transfers.
I think it's totally fine to have a wait period for confirmation, even though the coin doesn't need it.
Is there a trick to receive the confirmation email from Cryptopia? I couldn't register because confirmation email never arrived. (Yes, I checked spam)
Once again, thank you for making the effort and listing the coin!
