Please do explain how USD is completely irrelevant. BTS trades with BitUSD, OpenUSDT, USDT, which all track the USD. Please read back on the blog, and watch the videos to see why USD is used in many cases. Also if you look back, even one day, you will see @haejin usually includes multiple pairs of trade in a post.

Fiat is very relevant in crypto trading, because it is the only way to have a true value to any coin. BTC is measured off of the USD and other fiat.....and if BTC is the major pair for all alt coins, then all alt coins by default are being compared to USD or other fiat.

It is also prudent to have a way out of crypto when the market turns bear. In that situation, no crypto is a safe haven for your funds. Fiat currently is, due to it's barely and slightly wavering value.
