in my country gambling is ilegal
if traditional gambling can problem is law
Then you should refrain from gambling.
so iam prefered online gambling
Playing online does not exempt you from the law. It is still punishable if you get caught (which will happen in due course).
Even though it is legal traditional gambling will create lot of problem with the government because policeman will keep an eye on these activity but people who are gambling through online will has less effect from these policeman.
Wrong. The online activities of every person is monitored and thus even if you think you are out of the books if you are using crypto then you are mistaken. Thing is the authorities dont want to enter this fuss of online gambling and prevent it. Though in many countries they are increasing the stringency of laws.
