I have been investing in BTC for 4 years now. I have tried many sites, most end up closing due to getting hacked. I can confirm these two sites are the best out right now.
The first site doesnt even require sign up.

The 2nd site is actually poker with REAL players and not some bot that has edge on you.
Bet with these links to get bonuses

No sign up needed, bet away
Direct Bet

And this one for legit poker
