If we could have a PayPal option to buy cards with USD would be a total game changer and would likely see mass adoption of the game. I personally have a few friends that have started playing the game but are tech illiterate and trying to walk them through the depositing method of Coinbase to Blocktrades to Wallet to Market is really quite difficult.
If you could add PayPal as an option then I honestly believe the game will see mass adoption of people that aren't necessarily into crypto currencies.
Thanks,
