America is slow. Bitcoin betting has been huge for a couple of years. I started looking into Bitcoin at $15 when US started going after all the books. It was clear Bitcoin was the future in the industry. Glad you guys are finally catching up. You won't go back trust me

Check out DirectBet for live betting and european sports. Nitrogen best for American sports right now. Instant withdraw too. By the way the "hold" you speak of is just waiting for confirmations from the blockchain. That is unavoidable. Although you can use blockchain.info for your wallet, and they don't wait for confirmations for your coins to become spendable so it really is instant.
