The most popular fiat to crypto service (Coinbase) is not available in Korea.

Actually, I should clarify. Koreans can make accounts one a variety of other crypto to crypto exchanges like poloniex or binance, but the bottleneck which causes Korean crypto prices to be higher than other places is that Korean can't open accounts on "fiat to crypto" gateways like Coinbase.
