Mainly for the purpose of remitting money out of Korea I am very interested in buying BTC, send out, sell and get USD.
If you are planning to use the bitcoin as a remittance you can use it but only in Asian countries because I heard that they are banning all US exchange sites.
However, you can still use it without any problem just make sure do it anonymously and use VPN to bypass or deal anonymously from South Korea to the US country.
Read the quoted below.
The US, Japan, & South Korea form the majority of trading volume for Bitcoins and other cryptocurrencies. However, in the recent months, the regulatory stand of South Korea has been confusing. The cryptocurrencies aren’t banned yet, but they are heavily taxed and the government is particularly against anonymous cryptocurrency accounts trading cryptocurrencies.
This has called for stricter KYC and AML laws but ICOs were straight away banned last year which might change very soon this year.
