You are so so so right xineohp. I'm sorry I know I'm late to this party, but it's what google gave me. Trading against an unstable currency (BTC) is suicide... well, it's not suicide when everything is 10x-ing, but in an unstable market, you need to normalize it somehow when making trading decisions. If BTC drops 2k in 24hrs, and you see... i dunno, XMR posting massive gains against BTC, you jump in right? Welp... not so fast, you could still be losing money if BTC is falling fast enough in the same period.
This is so much more important if you're trend trading. In fact, if you try to swing trade without normalization, you could find yourself way way up a creek. I was thinking this from the get. Glad there's someone out there explaining as well has you have =) Happy trading everyone.
