When GCs first come into the game (I think about 4 yrs ago) the rate was about 1.6T per 1 GC.
Of course, though, people's profits and spending are much less. Military spending is also much less. Wehn they first come out, Cyriac had 3kT in cash. Then they brought financial services in to push us into reducing the large reserves vets had built up.
I make 600B a month from my main where as that could have been 3T in the past. The figures have changed dramatically over time.
I'd only be concerned if I needed to buy lots of game money.
