point of main, holding need long time but trading is short time which you can make money everyday from trading.
First of all you need to understand holding or trading everything you need to have knowledge. As an experienced trader earns a lot of money by trading daily. On the other hand if a good investor can buy good currency then he can also get profit.
In as much as there are big chances of making huge money on trading there is also higher chance of losing everything within a space of hours because trading has to with a lot of knowledge and experience that will enable you to understand the fundamentals and technical analysis of Bitcoin and even knowing all those things there is still a higher chance of losing your money.
But however in times of Bitcoin holding you don't need much knowledge before you could start holding and also with holding you will have a relaxed mind and free from panicking because your target is holding for a long time, however those that normally trade use to go through a lot of emotional trauma if there trade is going against there direction.
