Pairing altcoins with bitcoin is a mess, all this alt-roller coaster could be prevented if tether as a project wasn't so sketchy. At least there's now a new Tether like project in the works TUSD (True USD) supported by bittrex and other major exchanges, this could bring a turn around in price making with alt coins.
Pairing Crypto with USD/EUR is out of the question, its too vulnerable, i rather have all digital assets like TUSD or Tether and alt coins.
