For some time now I've been pondering on this matter, because I see similarity between bitcoin trading and gambling, so I'm wondering whether they're the same thing...
...
So having made all this comparisons, do you think that bitcoin can be classified as gambling?
I am going to speak from my experience and I believe that there is more similarity between certain types of "gambling" such as sports betting and poker and trading than between the classic casino gambling, in which there is a mathematical certainty of losing money in the long term.
In trading, as in sports betting and poker, you can lose money but with study, patience and effort you can make money in the long run.
I would say that to the extent that someone gets into trading following the fashion of the moment, with little knowledge and using a lot of leverage is gambling, but if you take your time to study, test and manage a bankroll, or as they say in the field of trading, is doing something more like what the winning players of poker and sports betting do.
In fact, a while back when the poker tables started getting tougher I saw people say on poker forums that they were starting to try trading, but I don't know how they got on.
I can agree with your comparison of bitcoin trading and and sports/poker gambling, the three of them requires acquiring special skills to earn money with them. Just like when you're required to study the events that determines the fluctuations of bitcoin, you're also expected to know about clubs and abilities of players in a particular season to know if it's favorable to bet on them, then poker, just like chess, you need special skills to be able to master the game and win.
Unlike the classic casino gambling, where you don't need any special skills to gamble, it is very easy for people to lose their money. I classify this types of gambling as "try your luck" because you stake your money and rely solely on luck to win.
