That could be cool and feasible, but I wouldn't call it trading cards, but it could be cool to have like things you own and battle and stuff like that...
I had in mind specifically sports cards, but I had also thought about things like Pokemon cards. Is that what you have in mind?
I was thinking magic the gathering I had some of those as kid and i remember the battles were cool and fun. Sports cards would be cool, but I mean I have sports cards and I see them gaining in value, yet I think the only way if these digital cards to gain value is hoping more and more people jump on just like bitcoin. And I just don't know if that would happen.
I see exactly what you were thinking now. That would be really interesting.
And, you're right about the needing more and more people jumping on board.
