since everyone knows that gambling is a better way to loss you btc or money at gambling sites . but trading is not liked by many persons due to mind hardwork of rise and fall of rates of bitcoins .
so better to stay in trading.
Trading is popular for a legit way of making or growing your bitcoins. But it takes time to earn and you must really be patient with it. And in gambling it's like a place where you can earn that quick but the disadvantage is you can also lose very quick. And it can even make you bankrupt and put yourself in a disaster when you get addicted.
I think trading profit is high if you know what you are doing, the risk in gambling and trading is very similar (but in trading you can decrease the risks by being a skilled trader). Some people say they can make 1%-2% profit daily with their trading skills. Gambling profit could be higher (as people try to double their money in one day or so) if the gamblers didn't lose more than they earn, and that is impossible to avoid even with skills...
Both has the possibility that you can earn high profit. In gambling, not all the times are sweet sometimes it's bitter. But there are times when you suddenly became lucky, you can win higher than the usual amount you are earning with trading. Your one week trading profit can even be earned on a single sports bet depending on the odds.
