Oh, there we go again. I thought with the merits being introduced, some of these shit posts would have reduced a lot by now. How does this have anything to do with what the OP just asked? Gambling sites, really? For someone who is looking for where to buy a huge amount of bitcoin ?

Anyway, I will say the OP may not really get a definite answer here as it all depends on the country of location. However, there are several exchanges that can easily give out that amount as long as the person making the transaction is verified, otherwise localbitcoin or other P2P exchanges should be good enough to boycott the whole KYC idea but at your own risk.
