I myself am an adherent of technical analysis
. I consider this to be the best strategy. But don't forget about common sense. The market is not predictable, ordinary traders don't know about pamps and dumps planned by whales. Therefore, graphs can show one thing, and reality can be different. Sometimes it turns out that the best strategy is to hold.
There is also a category of people who can not or do not want to learn and learn anything, so it's easiest for them to buy coins and hold them. The main problem of these people is laziness.
And someone just doesn't have any sense to study something, financially they feel good. It is convenient for them to buy and hold. And after a while they already decide what to do with coins.
So we always need to consider that in the crypto currency there are different people with different financial capabilities and personal qualities.
