What's odd to me is people are afraid of KYC so much. Why? Do any of you think that those evil people who want to steal you identity haven't done that yet? There are so many ways to do it besides asking about it openly on a gambling site, you can't imagine. Just relax, submit KYC level-1 and move, people. Live easier. 
People who wanted anyone's identity can just go to the government register office. He can just bribe the personnel there and get the full history of the person. If any of us think that our identity has yet to be compromised, think again... With all these government system hacks, private company database hacks, and insurance database hacks, do we still think that these bad people have yet to get our details? How about when we buy stuff online? I do not know why too many people are so sensitive about KYC. And if I don't want to undergo KYC, I'll just stop using their services, why do we have to make all of the drama about KYC? If we want to use anyone's service specifically in gambling, we follow and respect their TOS.
@Luckmcfly, in gambling there is no game without luck. That is the truth. Whether it is a sports betting, blackjack, poker or slots... all these game needs the element of luck in order to secure a win. Just for example, if one is not lucky even if he has the strongest four of a kind, he can still be beaten by the opponent if the person happens to have a straight flush. Aside from that the initial card distribution has a huge effect on the gameplay. Now I wonder what is the relation of chess and poker..., they are very different games, even a chess grandmaster may have a hard time winning in poker if he happens to face a good lucky player.
curious to hear your friends strategies on the roulette since this is way more luck, are the strategies related to bankroll management?
My guess is a little bit of bankroll management and a huge bit of luck.
I wonder if the successful ones, that end up beating the house and walking away with a lot will just keep playing until they win and stopping after a big win, or if they do it in a different way
because I see many cases of people who can't stop playing and end up giving all their money to the house or to other market participants.
Can't determine the accurate action done by a person regarding on that cases since usually experience gambler which have discipline usually walk away after they win huge since they know what will happen next if they decide to continue.
Usually this continuation of their gambling activity after they get a big win happens on newbies or have little experience on this situation since usually there luck will continue and they can receive a lot more that's why they end up on more risky situation and on verge to lost everything they won including their capital used. If they can't afford to lose much better for people to think about what are their priorities so that they can set up some threshold or plan towards their gambling session to avoid any huge lose or anything that can cut off their chance to secure their winnings.
