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.
The most possible scenario that might happen is, if you are winning continuously then you might hit the bell and will be asked for KYC. Should be an easy task for you.
But it's not that easy for that bell to be hit. We are talking about
"continuous" big withdrawals here for maybe a figures of
BTC0.1,
BTC0.2
(disregarding BTC price) etc. But for the total sum in the long-run, it won't be alarming.
But honestly, you don't have to worry about that at first as if you are sure you will have a continuous winning on your sports betting journey.
