Has anyone mentioned betting arbitrage? It's a long thread, there might be some mentions about it, but if there is nothing, you can do some research on that.
You didn't post anything since 2016 and the last thing you came up with is betting arbitrage!
Do you think there is a gambler who doesn't know what gambling arbitrage (or arbing) is?
Let me tell you that most of who have read your post know what arbing is but they know it's not worth it (risk if getting banned).
