About return on investment, it might be a loss for a long time for people that invested at the wrong time. Example are people that invested at $50000. But bitcoin is still going above $50000 again. Even above $100000.

The most important and most difficult issue is that stopping and not gambling often seems very difficult for anyone, even, I think, for the average player.  It is not easy for any player to stop playing abruptly, because all the same, this player is constantly and constantly drawn to play and try again and again to win back his loss.  But the probability of this is certainly less than the probability of gradually losing more and more.  So the moment will surely come when the player will still have to decide - to stop and stop playing or continue to play and get already serious problems in the form of addiction, family budget disruption, scandals with his wife and relatives, and so on. 
Unfortunately, this is the path of a very large number of gamblers.

Anything that goes well above the threshold of normal can mean abuse, so gambling isn't really something that's far off from that. There are a lot of people that are 'abusing' their freedom with gambling and ended up racking debts that are obviously not attractive. Moderation and control in everything that we do is the key to not resulting into any "abuse" that will be harmful to us along the way. What simple fun to us could mean a lot of danger in the future if we keep things unchecked.

To be honest, I don't know if it's possible to reduce an addiction. A friend of mine, a former gambling addict, once told me that addiction is such a thing that you either have it, or you don't. You can't reduce it. He was cured by a professional, and he has no addiction know, and I'm happy for him, but it's from him that I know that only a good professional can help you to end your addiction.

It won't be strange for us that some gamblers may have several accounts as long as they have a lot of money to become VIP members and enjoy the bonuses they get from each different casino, just like OP playing at big and trusted casinos on this forum like Stake , as long as he is an active gambler of course it will make the wagered higher and bigger, of course it takes time for them to get VIP members.

It's not as easy as we imagine, that every sacrifice of becoming a VIP member is clearly a lot of risk, let alone a lot of money and time spent being there. I'm just a small gambler with small bets. It will be difficult to catch up on getting a VIP account, even though the opportunity is there, but at least it takes years to get it.

I have heard and read about people gambling because they had no source of income,  a job or they wanted to add gambling as part of their streams of income. Whatever your category the bottom line is that we all gamble to make money though some group claim it's mainly for fun. But who would want to be losing money all in the idea of catching fun!

That is very clear and simple, all fields will have their own risks, and the two fields referred to here are gambling and trading in my opinion both have a very similar risk impact where psychological and mental will be the main targets that someone can feel. As for gambling, I agree with you that the level of risk in it is very high if you are too excessive in it. The self-control factor is very important in both areas, but there is indeed a slight difference in that the self-control factor in trading as you mentioned, requires one to have risk management, including stopping loss, take profit, maintaining psychological calm and other management to prevent us from what is called MC. Furthermore, in gambling, there is no risk management as I mentioned above, but from a psychological point of view, it is still very much needed here, where control in gambling is only needed when you experience defeat.

Of course, in any country, every parent will definitely monitor and track the activities of their children, but unfortunately there are still many parents who don't really pay attention to what their children are doing, so many underage children have entered and tried to gamble.
If the gambling habit has been left on, it is very likely that in the next few years they will lose their way in life because they have become a gambling addict.
The development of the era cannot be the main reason why many children are getting to know gambling because the biggest mistake lies in parents who are negligent in supervision.

Your best bet would be is to finding someone from this sub-board who is willing to compromise their anonymity and receive INR through their UPI ID and thereby sending you BTC/any crypto in return. As of now, @pawanjain is the only candidate willing to go ahead with this since their thread pointed out to a possible solution to this specific issue but other than that I can't find someone who is trusted enough.

Honestly it all comes down to parenting.  Here in the United States if you've got strict parents that heavily monitor your online activity, then it's highly unlikely that children are going to be able to make it possible for themselves to gamble online.  I know when I was a kid my parents would have never let me, they guarded the PC well.

That said if kids have parents that don't care, it's probably going to be pretty easy to get online and gamble.  Parents are the key.

Well, have anyone done the math?

Let's say you gamble $300 per day (yea, I know most people do not have that money) and you played every day for say 20 years... and then suddenly you win the Jackpot of say $2 000 000.  

So... over 20 years you gambled away $2 190 000 to eventually win $2 000 000. (Remember... you win and lose, but you kept on gambling, so you lost whatever you won too)

Yes, it was a time killer and entertainment for some people.... but the more you play, the more you lose and the losses added up, eats into your big jackpot some day in the future.
