First of all, please move the thread to gambling discussion like as airdagon said.
You can check out sportsbet, other than this, you will find ETH bet option no where.
You can move it by clicking the word 'move' on the lower left side of the screen.
The title and OP is contradicting. If you find difficult in using eth for betting, why not trade it to bitcoin and you'll find a lot of sportsbook site. Most of the gambling sites majorly accept bitcoin than any other currency.
