Bots Be Botting: South Korea Catches 30% of Crypto Trades Running on Autopilot (And Some Are Full of It)

South Korea’s Financial Supervisory Service (FSS) just dropped a truth bomb: API-driven trading now makes up about 30% of all crypto transaction volume. So, turns out, a lot of what we call “the market” is just glorified scripts arguing with each other—some of which are outright lying through their digital teeth.

The regulator’s sounding the alarm that automated trading tools aren’t just crunching numbers—they’re being weaponized to fake volume, spoof prices, and generally cosplay as liquidity. Tactics include placing tiny, repetitive trades like a bot with ADHD, spoofing non-existent demand, and multi-account tag teams that act like they’ve got insider info (or at least a group chat on Telegram).

FSS investigators are now dusting off their digital detective hats, zeroing in on accounts that scream “I’m not a person, I’m a bot army.” If your trading pattern looks like a hyperactive squirrel on espresso, expect a knock from the financial cops.

Manipulation playbooks
The FSS didn’t just wave hands—it spilled the tea on how degens are rigging the game. One classic move: spamming micro buy-sell orders in a loop to make a coin look hotter than a K-pop comeback tour. Another favorite? Pumping limit orders above market like a reverse Dutch auction nobody asked for, just to lure in FOMO-fueled normies.

In one case, a trader unleashed API orders from 5,000 won (~$3) to 10,000 won (~$6) in rapid fire—basically the financial equivalent of fake Instagram likes—then cashed out as retail piled in, blissfully unaware they were buying the dip created by a script.

Another scheme involved setting a moon price and then stair-stepping buy orders like a bot playing Jenga with the order book—each higher bid a tiny shove toward the target, until the price tipped and the bagholder brigade arrived.

The FSS gently suggested investors stop copy-pasting random HFT code from crypto forums like it’s a free lunch. Also, if a coin spikes for no reason other than “vibes,” maybe don’t treat it like a diamond hand moment. Just a thought.

Cracking down, but gaps remain
This warning comes as South Korea finally remembers it’s supposed to regulate crypto, not just watch exchanges implode like poorly coded smart contracts.

On April 7, regulators mandated exchanges sync internal ledgers with actual holdings every five minutes—because apparently, some were running on “hope and prayer” time. The move follows findings of delayed audits and trading halts that kicked in about five panic attacks too late.

Meanwhile, the Financial Services Commission is patching loopholes in withdrawal-delay exemptions—turns out, bad actors were abusing fast-track withdrawals like VIP passes at a club they shouldn’t have entered. Surprise: most voice phishing losses trace back to these so-called “exempt” accounts.

But enforcement? Still running on legacy bureaucracy. On April 9, a court reversed a partial suspension of Upbit operator Dunamu, citing, and we quote, “unclear rules.” So yeah, regulators are trying to shut the barn door, but the horse not only left—it’s now running a DeFi farm on Ethereum L2.
