Since a growing number of online sportsbooks, poker rooms and casinos now accept bitcoin, I've decided to give the crypto currency a try myself. Seems like it is becoming more and more popular in regions where online gambling is prohibited like the United States. There appears to be a wide variety of wallets available for Android and iOS devices so I'm a little unsure which one I should choose. Can any experienced bitcoin gamblers give me a little guidance on this? Coinbase, Blockchain, Circle, Xapo?
