It's not possible to know with sure how much profit we will make with trading. Nobody can knows with 100% sure if that coin will increase its price in the future, maybe the prices can go down and you lose your investiment on this coin. I think that is a unpredictable job, it's not very dangerous like gambling, but it's not so safe like buy BTCs and hold it.
Trading is an investment so there is really no assurance on how much you can earn with it. And it depends on the fluctuation of the coin in the market and that is why trading is unpredictable job, I think it must not even considered as job because that is just a sideline, but well there are a lot of people depending on bitcoin trading and treat it as their job.
This is true, learning trading would be really an opportunity to make profits and good money with it as long you already gained knowledge with it but its not an easy thing to achieve though you would really need experience and enough knowledge in able to sustain. Remember the risk of lossing money is still there.
I do agree with this, it is very tricky and unpredictable job to do because it requires a lot of patience and you must be open minded. You must have the skills to deal with it the rise and fall of the trend of trading monitoring as it requires time to watch over on your investment, which is not easy to manage with. Even though you are gaining good profit to it it doesn't mean you're confident enough to think that its permanent, there were times you experience downfall of profit. As we all know things in every situation deals with risk at all time, all we need is a focus and again as I've said patience.
Just like me, what I just did yesterday was very unpredictable I am promising to myself that I won't sell my bitcoins but it just did happened because I am sort of panicked when I saw the price of bitcoin is falling. That is why trading is really a very unpredictable and hard job if you are just going to depend on it.
