ShadowCash has been a favored project of mine for a while, along with several others. My point in focusing on it towards the end of the article is because this cryptocurrency has many of the attributes that I look for when selecting long-term holdings. There are several others I have in mind that fit the criteria quite well too, a couple of whom i've mentioned, but SDC is one of the more prime examples. I think platforms like ETH(or ETC), FCT, NXS, STRAT, MAID, LSK, SC, etc. could also be in this camp--some more so than others. And certainly there are additional cryptocurrencies i've left out, for the sake of brevity, but I list these so you get the idea.
