having funds in an account then no delay like that. Shame as I do love betting with Ethereum!
If you bet with BTC instead of ETH, using your own wallet, your bet transfers will arrive and confirm faster.
It's a matter of a few seconds from the time that you click "Send" on your BTC wallet to the time your bet is confirmed.
This period of time is equivalent to the in-play delay that is imposed by other Sportbooks with accounts, so there isn't much of a difference.
