I've had this account for 2,598 days. It had 1 million coins (max cash) and I spent some of it, and am left with 898,849 coins. Still quite a bit. Some cool items in inventory. A lot of puffles, and more! No black marks, no bans. Completely clean account. Just sick of the game, being 18 years old.
An account with coins is completely useless. Your $40 asking price should be a 40c BIN to be completely honest with you.
