This is something I don't get. If these bookmakers are going to suspend or restrict my account in the case of profiting too much, why should I even bother with sports betting in the first place? What's the point? Having fun while losing money?
Which leads me to the question, are there any reputable bitcoin sports betting exchange sites? And will they suspend/restrict my account too if I profit too much although they won't be affected by my winnings so logically they shouldn't care about it. In fact, since the pool and liqudity get bigger they should even support it. So, is it really the same case with bitcoin exchange sites too so that I should give up betting if I plan on winning in the end?
I made an account and profited from a good bet and instantly cashed out, did the same 3 times in a row. Always cashing out right after winning without any problems. In my opinion shouldn't have any problems either. It might depend on the sizes of your betting but overall I don't think there should be any issues.
The size of your bet matters, but let's say you'll win like 1 btc or more, I guess some gambling sites will already be triggered with the amount, and if they are really a site with bad reputation, they might not release your money and will accuse your of violating their TOS, that's usually their defense to flip the real story, so be careful with choosing a gambling site to gamble with, especially if you are betting with a decent amount.
Only if the bookmaker might think that you are cheating or abusing the system.
They should have an evidence, otherwise, their action is fraudulent.
