First of all I want to thank you for your efforts who have written at length and straightened the understanding of the law of risking money in Islam. A little input for you, you should give a little variation in your writing, so that it is easy to read and easy on the eyes.
To sum up, to me, it cannot be said that "each staking model is haram". Each staking model should be examined by thinking about why interest is haram, similarities, differences. Please do not forget that this is a new economy and technology. Before saying that something is haram easily, Muslims should consider it "thoroughly". I think the former behavior harms the advancement of Muslims.
Yes, this has been discussed above, not all bets are haram, but Muslims must respect the rules that have been determined in Islam, even though some people are still violating, but it will be his business with his god.
