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?
You're probably reading too much about those negative thoughts/reviews about sports betting sites may it be about suspending or locking the funds surely there are reasons behind that. Try to read sports betting sites articles that are proven reputed and established in the industry they are everywhere and even here I probably you can find one, I recommend BTCGosu site for the reviews of those reputed ones.
I don't think that a site will restrict you if you're winning too much and if you're that doubtful try not stay your balance in a gambling withdraw it as long as you're done. More than that you should read the terms and conditions of the site first before you play on them surely you could read there what are do's and don'ts rather than complaining a lot when you haven't yet started or trying.
