Re: which are the safest sportbooks to play?

Unfortunately, the most stable and safest site I know is not crypto - Pinnacle. They are not banning or limiting players, even the whales.

Pinnacle is one of the most known sportsbooks that has ever existed but it's also accepting bitcoin.

And you'll see that they have a logo of bitcoin.

For crypto betting, I trust most in Stake.com. The second place is going to Playbetr.com.

Both are good bookies that we have and there are others too, just browse on this section.
