You can make some good money with play chips. Sites usually buy your chips ranging from 1$-1.5$ depending on how much you sell.
They have Play SCOOP tours and sunday majors like Sunday Billion which are really fun to play and have a really big prize pool.
I bought some play chips on ebay 11$ for 15 million, played a bunch of tours, 3 weeks later, I ran hot and got 4th place in a Sunday Billion for 85M. I sold 100 Million for 110$. Just bink a scoop event for some high stakes tours and you can make some money.
Imo if you want to make some money with play chips, buy some first, (look around on ebay, you can find them for alot cheaper than stars) Dont grind from 1k to x million, it takes ages. Games are really soft, players are idiots, and I dont go on tilt when I lose
