Where are the korean arbitrage bots? $5.36 in BTC, and $6.58 in KRW, on the same exchange! Come on, it's your time to shine!
By the way... Koreans made Monero blow up from $30-50 to $400. Monero's biggest exchange in trading volume is Korean (Bitthumb, 30% of the total volume!), Upbit 8th. Upbit is the only Korean exchange to list Steem. Maybe Koreans just enjoy investing a lot of money, into good projects...
In my humble opinion, if you want to launder money with cryptos, use Monero, not Steem! Monero is the most private of coins, and its huge market cap/trading volume allows you to be much more discreet about spending tens of millions of $!
