I buy one of the DLC kits from steam that gives platinum that you can't trade. So after buying some stuff, I'm left with 100 in non-tradable platinum.
Then I buy 75 platinum from the website that I can trade with people, so now I have a total of 175P.
My question is; does the game distinguish these? Like if I buy a blue potato from the store worth 20P, does it deduct from the tradable or non-tradable platinum first? And is there a way to know how much I exactly have in each when I trade stuff?
Are you sure about that? I once read that you can only select the tradeable plat in the trading menu. So that way, you would actually see the amount. I have not been able to test that myself yet, though.
nontradeable plat is still visible in the trade menu when selecting plat; however, you will not be able to add it to the trade amount. ex: if I have 20 in tradeable plat and 20 in nontradeable plat, when I am selecting platinum amounts to trade i will see 40 plat in total but will only be able to select up to 20.
