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.
Your stat could be higher or lower because there is no available data to rely on but your assumption that most gamblers are still not Bitcoin investors could be wrong
if a gambler plays on Crypto casinos which are popular platforms for online casinos, he will see the full potential of Bitcoin, and being a gambler who wants to make a profit he is likely to invest in Bitcoin since he is a gambler, there's a big probability that he will use Bitcoin to deposit and bet, so we can say that gamblers are most likely Bitcoin investors.
