Yep, I do go deeply into fundamentals as well, will be posting a comprehensive fundamental analysis soon about one particular asset which I find to be massively undervalued and yet has the potential to be massive in the very long run.
I hold the most promising ones, trade the rest, but always up for a good long-term hold if the fundamentals are just right and the asset is trading under its market value. There are a couple of nuggets in my opinion. Will make a post as well on what I'm eyeing and why.
I'll also trade assets I'm holding. I'm holding Sia, but yesterday was an example where I do trade. Buy the rumour, Sell the fact. Re-enter lower. If the devs play ball I'm in for it.
