Lesser risk in trading if you know what you are doing, if you completely understand the market, else, it just like gambling where you are just leaning with your luck and if that's not favor your way, it will turns out losing your investment.
A time frame is essential in discussing which is more lucrative. If it will be based daily you can earn more into gambling since its more about luck and less of a chances where in trading you manipulate that chances for your favor, you can earn as much as possible in gambling instantly as long as you're not scared of losing. The conclusion is gambling gives more profit but has higher risk while day trading gives you more chances of earning and less risk.
You can always wait for the bullish trend and withdraw for profit. There is always a chance for some crypto currencies to go bankrupt but one is less likely to encounter such downfall with a bit of research.
This makes day trading for me more lucrative, it doesn't necessarily give you more profit rather it gives you different paths to manipulate your capital while in gambling you only have 2 end roads which is either profit or loss.
It's gives you more opportunities in terms of extending or adding more chances of earnings, unlike with gambling after placing a bet
you only need to wait what outcome will how up.
