Even this is true, you shouldn't make money from glitching. It just like trapping your customer.
Also this looks like a gambling to me, 10x in return or lost it all.
you do not get banned from this. You don't lose anything. The worst thing that can happen is they close your google play account for 2 hours. And there's like a 2% chance that will happen. I've done this plenty of times on my own account. I don't have multiple accounts only one. I promise you. No scam. No gamble. I'll even go first I really don't care I just need credibility.
