Well rich people who are gambling with bitcoins will never care about its price, either they win or loose it won't make any difference to them as its only a fun factor for them.
They don't care even they are going to lose as long as they are rich they are not going to think about their loses as long as they have still money for gambling.
That's the reality about rich people, but if I'm going to be a rich man. Then I'm going to be wise on how I am going to use my riches.
Instead of getting addicting with gambling, I'm going to get into investments.
