I feel like everyone should try blackjack, I know, I know, hear me out. Its not mandatory to fall into gaming addiction from every casino game ever, If you know when to stop, then you win against the system, but blackjack teaches you a lot of things, like to strategically think, to be patient and to take loss. I think its beneficial on many ways, but also very dangerous. I always recommend to read guide on how to play blackjack or history of blackjack so people will actually understand where did it come from and have a respect to a game.. 

I do too play online, coz I feel like I can end that anytime I want.. its more scary for me in normal /brick and mortar casinos... I play via a trusted casino reviewer,  which only has trusted casinos, so I don't get scammed.. I'll link it here too, so you can use it, my friend recommended this to me and I love it. It scans for licensed casinos in your country
