I completely agree this point that bitcoin is not for gambling but for making more and more money.
This is subjective. What may be useful to you may not be useful to another person. Its their point of thinking and thus they own opinion. You may feel
that bitcoin has a huge potential to give good returns in future while others may find fun in making it a method to "get-rich-quick".
It is better to quit gambling if you are gambling addicted. It will destroy your life and your future will be very worst.
A person who is addicted will continue gambling even after they lose a lot of money. It is because they need control over their addiction and nobody is there to enforce it on them.
Anyhow you can find online casinos that accept bitcoin but be careful because of the scams. Check their credibility before signing up.
Not all sites are scam. There are reputable ones running for long.
