Just as it works on other platforms, I think it would be interesting to have a wallet system on Twitch just as it does on the "bits."
That would lack the form of giving subscriber and would also create a "culture" of adding a certain amount of money per month in the wallet to give sub or buy "bits."

This suggestion would be feasible for people who do not have credit card and accurately go to the bank every month or every 3-6 months to renew only one sub while he could deposit an "X" value and spend as he pleased.

Sorry for English, this is not my native language.
