What percentage of bitcoin investors are gamblers ? Where will this figure be if we consider worldwide users ? I think it will be somewhere between 10-20% ? Also, it is possible that most of gamblers are still not bitcoin investors ? I see less chances of the later happening.
Most people who hold Bitcoin,the majority of them are sure gamblers.The reason is simple,the gambling industry being the most widely accepting Bitcoins as a form of payment and only few other industries are as open as gambling platforms to accept cryptocurrencies in general.That is why I think it is in the 70-80% of the users not just 10-20% as most people who hold a large amount of Bitcoins,also have some set aside to entertain themselves and what better way than gambling to have some fun.
Investors are people who invest in different businesses and I doubt Bitcoiners are also investors.
