there is no correct answer to this question actually. because it depends on you and you alone. profitability is not completely a market dependent thing. you may earn a lot in one market and nothing in another.
for example i have friends that are working in Stocks market, so i have also tried it and was never successful.
i tried bitcoin trading and i was more successful than before.
but then tried altcoins and i was really successful. but others prefer stocks still.
try them yourself with some small amount of money and see if you like things and how successful you can possibly be. then make your decision.
