It is interesting whether the ability to purchase GRAMS directly with credit cards will be implemented in the Gram wallet?
This is a fairly important function that will contribute to the popularization of the GRAM.
I did not see this in person but I heard from reliable sources that it will be BTC only at launch. So adaptation would be less then impressive in the beginning (no one except geeks and traders hold BTC).
CC gateways will come at a later stage. I am sure Telegram needs to find partners here.
