I know it's been said before, but these cards offer such great value. For example, 84s are going for around 32k on PS4. I just bought two platinum 84 CBs for 44k and 41k! Regular 84s will depreciate, but I get to use these great cards and get paid to do it! 84 platinum cards QS for 44k.
To be fair, this is one of those situations where the rich only get richer as you need coins to do this in the first place. After all, I'm sinking 44k into this CB for however long, but I'd rather sink 44k and have no possibility of depreciation vs spending 32k and face the real possibility of depreciation.
