As far as I know, now the best option is day trading, it is the most profitable if you analyze the course. But for this you need to have a good experience in order to manage to profit from this trade. If there is no experience, then you have to take a risk, or choose a long-term investment in cryptocurrency.
The best option is not day trading, the best option is actually what you know suits you best when it comes to trading. I wonder why a lot of people think that day trading is for everyone. As much as you can make huge profit from day trading, I can guarantee you can make a whole lot of losses before you even know it once you have no pretty good trading knowledge and great experience.
People are always so in a haste to make a lot of money from trading without learning and that is where they will always keep getting it wrong over and over all the time.
The habit of been on haste to make a lot of money was the reason why we see some people saying they are not favourable through crypto currencies. Day trading give good profit for those that have the experience and they also have time for their losses either but I don't like spending much time on trading.
