Gambling is profitable if you’re lucky enough to hit the jackpot and it will happen at no specific time.
In trading, we make money through our hard work, we do analyze the market as much as we could so we can hit our target profit everyday, or even every month. Personally, I still believe that Trading is more profitable that gambling though both are risky but in trading you can less that risk by analyzing the whole trend.
The thing is IF your luck will prevail which is less chance for it to happen, unlike trading where the result can be done exactly as what you have analyzed. Both can be risky but it will all depend on where you are more skillful like if you doing trading for a long time, making technical analysis, reading the market chart, and more then it would be less risky but if you are good at gambling like you are doing it for a long time, you made a good performance on your play history then probably gambling will be much perfect for you. If you want something lucrative then focus and learn whether gambling is or daily trade.
Besides the fact that I would never compare day trading to gambling, in my opinion both are useless and don't work. HODL is the only key to success no matter which trading industry you are into. Those who invest for long term never loose. See Bitcoin stats and you will get to know why HODL is so important.
I'm just thinking if you accumulate all of your profits on your daily trade wouldn't be comparable to the profit you will have if you go for HODL? Sure there will be some losses on it but there will be time bonus profit will come like 3-5x of it. Or perhaps it might not have the same amount of outcome but pretty sure it won't be that far. Besides, as far as I know, there are several people who can able to pull it through.
