Those picks are very weird and probably speculative. I would still prefer to choose monero dash verge xtrabytes and zash over all others as these coins proved themselves over time mostly.
If someone is investing in very low marketcap coins then they are speculating to the highest degree. The thesis is that one of them will make it through the trenches to the $1b+ threshold and make you a lot of money. At one point all of these coins had to start from the same place; low marketcap, only on crappy exchanges, no hype, skepticism over the product, etc.
