South Korea extends its crypto crackdown from app stores to 27 offshore exchange websites

An unregistered exchange that wants Korean customers has been losing channels one at a time. Card payments at unregistered firms were restricted in May 2024 ^[8], and registered Korean exchanges were told not to facilitate transfers to unregistered overseas operators ^[9]. The FIU's own sentence, as Cointelegraph translated it, places the website block in that sequence: "With this decision, blocking measures against illegal virtual asset operators will also apply to internet websites, following apps such as those on Apple and Google," the FIU said ^[2].

The two sources date the app-store step differently. Cointelegraph reported in April 2025 that downloads and updates were blocked for 14 unregistered apps on Apple's App Store, following restrictions on 17 apps through Google Play ^[20], or 31 app restrictions in all ^[21]. Crypto Briefing puts Google Play's registration mandate at January 28, 2026 and says it affected Binance and OKX ^[19]. Both can stand if the 2025 action was a regulator-driven block and the 2026 one a store policy; that is our conjecture, not either article's. Cointelegraph names nine of the 27 websites ^[5], so 18 are unnamed in its coverage ^[14].

The FIU's stated reason is user safety: asset theft, fraud and data leaks on platforms outside the domestic perimeter ^[12]. Crypto Briefing adds a price argument, that unregistered platforms reportedly average 1.5% to 10% in trading fees against about 0.16% at major licensed exchanges ^[11]. On a $10,000 trade that is $16 at a licensed venue and $150 to $1,000 offshore ^[17], or 9.4 to 62.5 times the licensed rate ^[16][15]. The article's own word for the averages is "reportedly", so we would hold them as the FIU's framing until someone shows executed trades.

In our view, registration is now the only way an offshore platform keeps the Korean market, and the door is narrow. Crypto Briefing says registration "appears to be the price of meaningful access" ^[13], and only 27 to 28 domestic platforms have paid it ^[22], so the 27 sites announced on October 13 ^[1] equal 96% to 100% of the registered field by count ^[24]. Crypto Briefing also concludes that price-conscious traders have little financial reason to leave the compliant ecosystem ^[23]. A regulator that adds a fourth control after payments, transfers and app stores is acting as if enough traders still reach these sites at fees many times higher, and we think that demand is what the block has to beat.

We would be wrong if the block turns out to be mostly declaratory: if the 27 sites stay reachable for Korean users, or the next batch is small, the fourth layer adds little to the three before it. Neither article describes how the FIU will check that the blocks hold.
