I have btc but never had to buy bitcoins.  I get bitcoins because i play poker at certain sites that allow you to cashout in bitcoin.  Thus if i deposit another method, they allow me to withdraw bitcoin.


But if i wanted to buy a lot of bitcoin... say at least 20 bitcoin... what would be the best method?  Coinbase and circle the limits are very small right where you have to wait at least 1 month?  Even if so, you could only buy 3k max worth of bitcoin?  I also wouldn't want to pay a premium for bitcoin and want to buy bitcoin at the current price. 



What about those that want $10000+ worth of bitcoin and more and don't want to pay premium fees?
