Nice article.
I've always been in the camp that bitcoin will prevail as the coin to rule them all, although there is plenty of room for others. For me, it' all about:
BTC, STEEM, XMR, SC, ETH
I see a future where it'll be pretty rare for one person to hold a whole single coin. The more bitcoin spreads throughout the world, the less volatile it will become, but more valuable.
+1 to the formatting suggestion too :)
