Hey, an investment isn't simply luck-based, there are decision-makings made behind it that actually contain reasonings and the like. Investments are pretty much 50/50, though you can skew the chances of you winning by determining which of the 100% of the w/l ratio you should take, unlike in slots where you bloody don't have any idea how to go in. The chances are the same, 50/50, but slots are something like no matter what info gathering, studying, and whatnot you actually take, the place you'd take in that 100% is completely random, one that you can never influence.
Afaik some people said their early investments in Bitcoin was a "gamble", and I'd never deny it. Just that, gambling in an investment and gambling in a casino game have different factors that separate them pretty much from that "luck" factor.
I agree it seems that people no longer see the difference between gambling an investing, and I cannot really blame them because sometimes when I see people in the forum saying that they are going to invest in all kind of new coins that we know are scams and that they know that they are scams too but they are willing to bet that someone else is going to come along the way and pay a higher price than what they did then those people are gambling, but investing in bitcoin is not gambling, there is a big difference there even if people cannot see it.
