Graphic analysis? no mate, that is quite old.
I just buy altcoins, and i hold them for some time because i like them, i like the dev's, the project, and how it is moving, not because of the analysis or something else.
In fact, i am just buying altcoins for long term right now, maybe that is more profitable than just buying pump and dump coins.
I would like to ask you what is the key criteria for you when you decide to buy an altcoin? Graphic analyze, project quality, news or any other thing?
