I hope I covered the main differences with this, if I missed something, reply and I will add it!
Sure, you covered a lot and many thanks for that. You know at some time I was considering patronizing poly markets because of its projected decentralization, thinking it is another casino environment, But I'm glad I stumbled on this now and I'm sure am never going there. I love the parlays and betting on outcomes that are certain how it operates in sports betting and not those clearly manipulated like you've outlined in prediction markets. Prediction market is another trading environment for sports outcomes.
Anyhow, is quite funny, when I make an informative topic about laws or rules or types of betting, the topic dies at 2 pages, when I create some like betting on Jesus, it goes to 5 pages in a day!
It is simple, most people on the gambling section are always in a hurry to complete their post count, and joining with the fact that merit isn't freely flowing here, They are not interested in reading meaning into posts in order to contribute beautifully. Your explanation holds much value, but it's long and only those disciplined to extensive reading would really want to patiently go through it.
