We have withdrawal limits because the vast majority of funds stored in Namebase are kept in cold storage. A very small percentage of funds are stored in hot wallets for withdrawals, bidding, etc. If we increased withdrawal limits site-wide we'd need to store more assets in hot storage and less in cold storage, which is ultimately riskier from a security perspective. Before convenience, our number one priority at Namebase is ensuring the safety of assets stored on our platform.
With that said, we're happy to increase the limits for customers who request higher withdrawal limits as well as help facilitate one time bulk transfers — please reach out in our support chat.
