I'm using
Vodds.com for my bitcoin and also with real cash but i would like to know if you can suggest sites that offers racing games and casino using bitcoin.
Try sportsbet.io. That site is very great, fair and easy to deposit and easy to withdraw and with the use of bitcoin. Most sites that are great are using bitcoin as a gambling money. I don't know about racing games like F1 racing but there is a racing game that is virtual in sportsbet.
