The most widely used Cryptocurrency?

First task this evening we must summon Snow White: Monitor, monitor on the wall, what’s the most widely used Cryptocurrency of them all?  Mirror says, it’s not Bitcoin. Mirror says the most widely used Cryptocurrency is Tether.  Of all the two thousand plus different alt-coins?  Yes, Tether.  The cryptocurrency you likely never heard of.  About a four-minute read. 

Comment: the article makes an interesting point – many people use Tether without knowing they do, as cash balances at Bitcoin exchanges must be held in Stablecoin.  Altogether, a fascinating article.
