Bitcoin mixer enhances privacy and resists attacks.
It is up to the laws of each country to determine if gambling is illegal.
Bitcoin in the case of gambling is also just a means to satisfy the desire to gamble and make money. Bitcoin in this case is not considered bad as the dollar or any FIAT is being used for gambling all over the world.
Bitcoin is only used as a tool for gambling and is not directly involved with the gambling industry.
Bitcoin is still Bitcoin, not regulated by anyone. it's just a payment option that is easier and more private.
Gambling sites that support Bitcoin are also increasingly appearing.
and about Bitcoin mixing, the last few months have been quite excited when Chipmixer was shut down because it was involved in money laundering crimes.
No wonder they are thirsty to be shut down, because they facilitate criminal acts.
Not all Bitcoin mixing sites do this practice, Many mixing sites still survive today.
Yes, bitcoin is a currency, a payment method, casinos have the right to add it to their form of payment, no one can ban them, and it has nothing to do with gambling.
As for mixers, you are right, not all mixers cater to criminals, what is going viral out there is just because bitcoin haters are spreading false information. Bitcoin gives privacy, and mixers make us more private.
