A temporary solution it will be actually but not one which you can always count on. In other to avoid restrictions and not allowing your account getting some reputation that will affect your funds and this is why exchanges should be used for the purpose of changing and trading of crypto assets, other third party services shouldn't be carried out often on exchanges, particularly the ones they mentioned in their terms, for funding of your gambling wallets, you can always do that from a non custodial wallet too and save your self the hitch that comes with the exchanges. These wallet sometimes charges even cheaper fees as compared to the fees exchanges do charge, so they are a better option.
