I'm a fan of scalping, as you you can make a good profit with the exploatation of micromovements without using too much capital.
But of course it's very risky, you need to be very good and... you have to be stress resistant, because it's a high level adrenaline activity.
Long term trading is boring, I don't like it.
.. Good, but don't you also prefer to HODL some coins in Long term?
Well, he can start from somewhere and if he knows how to trade, I will even advise he starts with that first and make use of the percentage of some of the little profit he gets to look for a good coin to hold. Holding is good, but trust mate, trading is a lot better to make some good profit and increasing what you have, even though risky, with great knowledge, you can do well.
Both day trading and long term trading can be profitable as long as you know what you are doing and you do not see trading as gamble but a real profession that requires a lot of work, effort and learning.
Day trading is very good but you are going to have to be stuck on the monitor each and every day and close the trade every day, but long term is easy as you only need to do quick analysis, set a position and then look forward to it. I combine both anyway, so it all depends on you.
