Most of those challenges many of us are having were caused by us through the ways we have been gambling and how we show our careless attitude towards it, its not a matter of using a physical gambling platform or the online version that controls us from having the best of gambling experience, its mostly all about what we do and how we acted towards many of these things in gambling in which could have negative impact on us.
May be that is true but what happened with the person in OP was something that he could not have controlled at his end.
If the gambling agent cheated him then that is not his fault. Same thing with online casino sites, if you deposit your money on the site and if the site is a scam then is it your fault in it ?
The two of you are right, of course, many issues are caused by gamblers, and in some cases as well, they are just victims of the circumstances. And if you read what @Dunamsx wrote, he never mentioned "all" but "many." Above all, the conclusion of the two of you is very valid and somewhat agrees as well, and I say that the two types of casinos are good, but no matter how good they are, they will have their cons too, if not many. I have replied many times on this thread and shared numerous pros and cons of the two, regardless, we should choose based on our preference and what we can handle and we should try as much as possible to gamble in such a way that any gambler fault is not from our end.
As for me, I like to do the two together depending on the mood. However, due to the nature and better accessibility of online casinos, I do it more. And if I should put them in a ratio, it should be more than the ratio of 1:100 (Land-based:Online). I said that because I've experienced the two, and till today, I've never experienced any reason to regret gambling through either of them.
