Trading and gambling is profitable for the experts,both is risky activity but little different
Gambling is more risky we can lose it immediately if we have no luck
In trading all depend on market condition
trading expert maybe can get high profit and i believe that because they are clearly can reading the situation and able to predicted when is time to buy and time to sell but gambling is different that you not necessarily be an expert to get high profit because even newbies in gamble is possible to win such as expert
Even professional traders cant really actually predict price movements on trading but yet they can able to point out not the accurate position but nearly the best possible spot to buy and sell which can really give profits even on long term basis. Gambling do really have different levels depending on what games you do play on knowing that there are skill based and pure luck based gambling games.
