And still there's no ingame-bonus for the Bitcoin cards, i have already 3,000 of them.
What was the plan for the Bitcoin cards anyway? I couldn't find any information. Is it worth upgrading them or better to wait?
That Bitcoin card is worth NOTHING in the game itself ... only the ingame_bonus should be worth something,
so ... don't upgrade that card now till there's an ingame_bonus
