I don't what you called this in your country or in English.
We called this "Last Two"(2 DIGITS) , "Swertres"(3 DIGITS) .
Currently they have this draw scheduled every 2pm, 5pm, 9pm (GMT +8).
If you will hit in 2digits, if you bet 0.20 USD, you will win 16USD.
In Swertres(3 DIGITS), 0.20USD bet will become 124USD if win.
Any idea where I can do this online and they are accepting Bitcoin or other crypto?
And also, any ideas or strategy/tricks/advices to maximize profits and minimise risks by playing this kind of gamble?
I do not understand the image/post clearly unfortunately. The lottery am used to in real world is quite different from this.
If this kind of lottery is truely gambling then minimizing risk and maximizing profit won't be possible because is about taking big risk (which is what gambling is). My only little advice is to bet few times with little amount (if that is allowed) that you can afford to lose, in order to minimize risk and see if you can be lucky
