your title tells me the article is going to help me learn how to choose a coin to invest in, so lets break it down.
the first two paragraphs are just explaining the problem not the solution. and contain some obvious yet not so helpful pointers in them!
so far the question in the title is not answered.

then the article suddenly moves on to a totally different subject. while it is an important subject but it is irrelevant to the subject and the problem at hand (which is not yet answered). it explains how to buy and introduces exchanges (completely off topic).

then it moves to another important but completely irrelevant subject: cold storage! so as a reader who saw the title and wanted that question answered now i am reading another irrelevant content here

finally it moves to something that is move relevant: Fundamental Analysis but i still say it is all over the place and too vague.
then to make things even worse it brings in TA but leaves the explanation half ass by only showing 2 charts!

sorry but i still didn't get what the title of your link to your website promised me
