for the sake of statistics for analysis and study, there should be 2 currencies, one bought and one obtained ingame via normal means :0
both would probably count as the same currency
there would be some conditions though, like the later being used up first before the purchased one depletes
another condition for gifting would be the opposite, whereas only purchased currency can be gifted (eventually with a transaction fee too! (profit for toonslab yay, more money for developers!))
Edit: nevermind, i was just informed that it is very unlikely to happen, might aswell post this here:
