Although there are some differences between the two, like most gambling depends mainly on luck. You play and let luck decide fate of the game, that is the risk factor, because the gambler doesn't have any control or influence to determine the outcome of the bet. Also a bitcoin trader doesn't have any control or influence to determine how the market swings, he takes the risk to trade his bitcoin without knowing the outcome whether it'll be profit or lose. The diffidence between the two is that a bitcoin trader can predict the market, while a gambler can not predict the outcome of a bet, except in sports bet.
So if a gambler where to go into bitcoin trading, do you think that the experience of taking risk in gambling will be an added advantage to face the risk of bitcoin trading?
from my opinion, if you say about risk, maybe its not just trading or gambling that is risky, maybe living in this world has risks.
next you say gamblers bet all their money in games where the outcome of the bet is unknown but what about sports betting as you said, is not that one type of betting? and if you compare with trade, do you only compare overall?
there are still a lot of deviations but I will say in conclusion that gambling is different from trading and if you say about risk yes you are right but you have to remember in trading there are 2 choices between short term and long term and on the one hand you bet $ 100 and lose on gambling at once you lose your money, but for trading, especially bitcoin, even though it is short term or long term, you still dont lose all the money you have.
trading is not gambling and is not the same as both have different risks and levels of luck.
