I kinda agree with Westbrook, we don't really need a trading feature but more of like a donate gralat kinda ordeal. I also don't see how it could be abused, Like Westbrook said you'd need to be identified, Have an X amount of hours.(Probably 24 or 50 hours ).
I mean if there is only way I think it can be abused(Not really but somewhat?....) And that's by making alts and doing the tutorial to donate, Which i don't see as much of an issue given that like above you'd need
A. To basically make new emails for every single account
B. Need wait like 1-2 days of CONSTANT online without logging off time to get itoff
C. It's only 250 gralats, You could literally farm that in like 30 mins and more.
Given all this, I don't see why or how a donate feature would hurt anything. If I have 500k in gralats and wanted to give my friend 3k for a hat, Id have to farm for it all instead of just giving them it.
