We could never know the exact details on how big the crypto gambling industry is right now we have so many gambling sites and it would be hard to track all of it since some of them are not regulated.
But I am sure that there are so many people who lose too much on it and there are some who live their dream lives because of it.
The gambling industry is so successful and the living proof is the old gambling sites that are still running up to this day and still making a huge profit because of it.
I have heard there are others building a new casino online because of this pandemic people are into playing online games. Is there really an accurate number? Those old sites are still running because they have the trust already of the users in terms of its security and continued improvement on their site. So we don't know indeed how big is the crypto gambling industry users since mostly these days of a pandemic for sure it is increasing.
Due to the coronavirus anything that can be done online is growing in terms of their user base, many of those that gambled at physical casinos are now using online casinos whether because they are trying to protect themselves or their families or because physical casinos are still closed on their country, and when we add the huge amount of stress going on many people that were not gamblers are gambling in order to reduce that stress and deal a little bit better with their everyday lives.
