Bitcoin made the gambling easier and faster than before , also when you gamble with Bitcoin , you will be anonimous , this is the answer if we asked why people like Bitcoin , and for that the Bitcoin casinos number increases every day , Bitcoin will be more popular not in gambling only , but in all other services , like trading and buy goods and online payment...
I think for now in my country its not anonymous we are giving our real identity for security reason and for laws and regulations in my country.. so i think in the future gambling here will reduce and will be decreases.. because of this regulation and laws..
So i think bitcoin gambling casino will not be popular in the future than regular casino..
