It is true gambling would be one of the main attraction of Bitcoin .
Crypto currency is the best for gambling sonce it have anonymity gamblers wouldn't worry about their identity while gambling specially for those who doesn't want their friends or family to know that they are gambling.
And for me the best crypto casino right now is
Stake since it have all of the games and it have so many give aways or challenge for us gamblers.
No,,, this is not true. You have to understand that public blockchains started out as private, but not necessarily anonymous. How can it be anonymous when you can tie certain transactions and certain addresses to an IP or an email address or a site and service or even in some cases an online identity?
But in any case, Stake cannot be the best just for having all the games and giveaways. You talk about crypto gambling being the best for being private, so should not the best casinos give you purely crypto options, have crypto provably fair and have complete anonymity?
I think you misunderstood the point of being anonymous here. How does it help someone if they find out an IP or an email address of a person? We have VPN for resolving the IP problem and anyone can easily create an email adress just for their gambling accounts. I think the biggest problem that people had regarding gambling before blockchain was the need of them having to verify their identity using their personal documents and also the fact that gambling is not allowed is certain countries. Bitcoin casinos now offer the possibility for everyone , from all around the world to enjoy gambling without having to worry about their identity or money being stolen.
One more important advantage of bitcoin casinos is the fact that they offer almost instant transactions, meaning you don't have to worry about creating accounts on different platforms like Skrill or Neteller(where again you have to verify your identity) and you also don't have to wait hours or days until you receive your withdrawals.
