If gambling was to be like a crypto origin then I would have said that Gambling is worth it but however, there are still people who it favours and those who think their luck is not in it. According to Encyclopedia Britannica online
"Gambling, the betting or staking of something of value, with consciousness of risk and hope of gain, on the outcome of a game, a contest, or an uncertain event whose result may be determined by chance or accident or have an unexpected result by reason of the bettor’s miscalculation."
From the meaning you could see that gambling involves a contest for a lucky winner to by chance as captured to take the prize of the contest. Which means that gambling
is not guaranteed for one to make profit but rather by chance if the odds turns in favour of the individual.
Bitcoin according to Satoshi
"Bitcoin uses peer-to-peer technology to operate with no central authority or banks; managing transactions and the issuing of bitcoins is carried out collectively by the network. Bitcoin is open-source; its design is public, nobody owns or controls Bitcoin and everyone can take part. Through many of its unique properties, Bitcoin allows exciting uses that could not be covered by any previous payment system."
We can see that bitcoin from the onset based on this explanatory from satoshi, Bitcoin is an asset so when it was turned into an investment, it was already foreseen by satoshi to be so and hence the price volatility which as well serves amongst the beauty of bitcoin allowing for more holders to be able to hold more and new entry as well.
I had to do this explanatory for a better understanding. We can see that bitcoin holds more potentials than gambling. Bitcoin has a long lasting life span and is not controlled by any individual but market demand and results to volatility which when utilized can fetch you profit either in the long or short term whereas gambling is controlled and possible game manipulation or glitch which might cause one to make loss without one knowing what is happening behind. So from this, you can deduce to know the possible answer. Anyone who has had the taste of both end would tell better which is f more harm than the other.
