Trading is highly profitable yet too risky so we can do trading in some of the best ways. First of all, we need to know the market really well because the market is highly dependent on news, when any bad news is released, no one prediction not working so before trading we need to be read about the market
Trading is profitable only for the people who got enough skill to manage all the technical things of trading and news and events occurring around the bitcoin ecosystem.
Not even have an assurance, even how good you are in technical or even fundamental analysis crypto market price still unpredictable and no one knows how to predict it in a right way. Not all good traders always have success and not all of them always win in the trading field, it seems it is also included in your luck which is good if you have it. Therefore I conclude that in trading there are prey and predator, that is why to bear in your mind that avoid always a prey.
Stock knowledge and gaining experience are still good assets in trading.
