I wouldn`t keep a large some of money in a btc sportsbook. Too many sportsbooks disappeared this year with users funds. I would look for a book with instant withdrawals and try to minimize the time you keep your btc in a Bitcoin sportsbook. Your bitcoins will be always safer in your wallet.

DirectBet does not require a deposit at all and your winnings are sent back to you automatically right after the event and sometimes during the event itself. You can also find high limits at DirectBet.

If you are interested in American Odds the switch is in the bottom of the right bar.

There are different Altcoins with different advantages and disadvantages compared to Bitcoins, for example lower transaction fees, faster transaction confirmation. But there are too many Altcoins that were born only for pump and dump purposes which give a bad name to the whole Altcoins industry including Bitcoins.

Bitcoins are great for Overstock or any other supplier that accepts Bitcoins, so they should consider giving a discount for payments with Bitcoins. That will also motivate more users to start using Bitcoins.

Last week DirectBet increased the bet odds and decreased the max bet size.

But you can still bet more than the maximum if you like. Read here how :
