Accumulate? Gambling can lead to reduction of your funds as well, so I wouldn't use gambling as a way to earn more bitcoin. It should be fun, or a social event. It shouldn't be seen as a way of making money, unless you're on a tournament level.
Gambling is really risky, if you are not careful you can easily lose everything you are having in gambling, but some people do take gambling as another way to make money which is wrong, am not saying anybody can’t make money from gambling, we all can make money but when gambling, their is no assurance that you are going to make money that’s why we all shouldn’t deposit money in gambling and have intention to grow the money, if you are not careful the money might end up reducing in price. Gambling should be don for fun incase if you win, you take your win and if you lose, then you will accept your faith, that’s why we should be able to control ourselves when gambling.
I'd probably keep all of my money on hardware wallets and either move somewhere else, or wait for them to rethink it.
The best thing is just to move money to hardware wallet, even if government ban crypto, they won’t even know you are holding any coin and you can peacefully hold it. Every government that’s against bitcoin currently won’t have choice than to support it later in the future, so sooner or later, all government will have to adopt bitcoin, they can’t keep on running away from the thought.
