Bank of Korea is not worried about coordination failure

BOK concludes that fiat and botcoin will co-exist:

“High costs of using fiat currency increase the demand for digital currency,” details the BOK research paper. “Similarly, high costs of using digital currency relative to fiat currency raise the demand for fiat currency. In a world of imperfect currencies with uncertain costs associated with the use of a currency, it is unlikely that the relative costs of using digital currency will be low enough to drive out and accordingly crowd out fiat currency entirely.”

Great, let's move on.
