If this were stocks, I'd agree with you.  But since it's coins, and the value of a each is determined almost entirely by bots, hype and whales... I think due diligence might actually be detrimental, as weird as that sounds.  I tend to make a lot of my decisions based on the chart, the volume, and the density of hype I detect on the internet.  What the coin actually does or what the devs are up to is somewhere between secondary and irrelevant.
