What Upbit announced

Upbit's notice, number 6653, is titled "깃코인(GTC) KRW, USDT 마켓 디지털 자산 추가", which means Gitcoin is being added to the KRW and USDT markets. It went up at 19:00 Korean time (10:00 UTC) and set trading to open at 19:30 Korean time (10:30 UTC). Only the Ethereum network is supported for deposits and withdrawals, using the token contract 0xde30…163f.

The notice came with Upbit's standard listing guardrails. For about five minutes after the open, buy orders were blocked and sell orders more than 10% below the previous close were rejected. For about two hours only limit orders were allowed. Upbit set the reference previous close at 0.00000217 BTC, which it gave as 246 won or 0.1818 USDT. The single-withdrawal limit is set at the equivalent of 100 million won twenty business days after listing, and deposits must come from exchanges on Upbit's travel-rule list or from personal wallets that passed its ownership check.

Upbit describes Gitcoin as a DAO of open-web developers that funds and builds open-source tools, data and AI models as public goods. It raises money through quadratic funding, a model where the matching pool grows as more individuals contribute to a project, and GTC is the token used for grant allocation, dispute resolution and treasury decisions inside the DAO.

This is the second Upbit addition in one day that moved a token by roughly half. Earlier on Monday Upbit listed Reserve Rights, and we covered that move in Why is RSR up 46% today?. The pattern is close enough that the RSR piece is a useful guide to what happened over the following hours.

The move, fifteen minutes at a time

Binance's 15-minute spot candles show how fast it went. GTC traded around $0.166 before the notice. The 10:00 UTC candle, which contains both the announcement and the Upbit open, opened at $0.16579, spiked to $0.393 and closed at $0.34045. That is a 137% gain from open to high and a 105% gain to the close, all inside one candle. The next half hour held above $0.34; from 10:30 UTC the price slid to $0.272, bounced to $0.339 around 11:00 UTC and drifted to $0.293 by 12:51 UTC.

Binance's 24-hour ticker put spot at +61% and the perpetual at +52%. NexuAlpha's own market feed listed GTCUSDT as the day's biggest mover at +54.5% on $165 million of perpetual volume.

On Upbit itself the KRW market peaked at 494 won and traded at 393 won at 12:51 UTC. Using Upbit's own KRW-USDT price of 1,348 won, our arithmetic puts the peak at about $0.367 and the latest price at about $0.292, within half a percent of Binance spot. Upbit's KRW book turned over 49.5 billion won in under three hours, about $36.7 million by our conversion, more than twice Binance's 24-hour spot volume of $14.9 million.

Why futures are the part to watch

Futures did most of the trading. Binance's GTC perpetual turned over $165 million in 24 hours, about eleven times the spot volume, and $94 million of that changed hands in the single hour after the notice. Open interest on the perpetual rose from 21.1 million GTC ($3.5 million) at 10:00 UTC to 34.5 million GTC ($9.6 million) at 12:00 UTC, a 63% increase in coins and a 2.7-fold increase in dollar value in two hours.

Most of the new positions are short. Binance's account ratio for the contract moved from 44.8% long at 10:00 UTC to 38.3% at 11:00 UTC and 39.5% at noon, so roughly six in ten accounts holding GTC futures are betting the move fades. That selling pressure shows in the price: at 12:51 UTC the perpetual's mark price was $0.2769 while the spot index stood at $0.2940, a discount of about 5.8% by our arithmetic.

The discount is why funding went to the floor. On Binance, a perpetual trading below its index pays a negative funding rate, which means shorts pay longs. GTC's contract settles funding every eight hours, and Binance caps it at plus or minus 2% per settlement. The two settlements earlier on Monday were tiny, -0.0035% at 08:00 UTC and +0.0069% at midnight. The predicted rate for the 16:00 UTC settlement was -2.00%, exactly the floor.

In plain terms: anyone short GTC on Binance at 16:00 UTC pays 2% of the position's value to longs at that moment, and if the discount persists the same applies at midnight UTC. On a 5x leveraged short that is 10% of the margin gone in one settlement, before any price move. We could not find a GTC perpetual on OKX, Bybit or Hyperliquid when we checked, so Binance is where this funding squeeze is concentrated, and the funding-rate board is the quickest way to see whether the discount is closing.

How to act on this

Chasing a listing candle is how most retail losses on days like this happen: GTC spot printed its high in the first fifteen minutes and has been lower since. If you already hold spot GTC, the question is whether to take some profit while Korean volume is still heavy, not whether to add. If you trade the futures, the funding clock matters more than the chart; a short opened now pays the -2% at 16:00 UTC unless the discount closes first, and a long collects it but sits in a market where six in ten accounts are positioned against it. Keep leverage low, set the stop before entering, and check our funding-rate board before each settlement. If you trade it on Binance, signing up with the code 11350287 returns 25% of your trading fees, settled hourly, which matters on a contract this volatile where people tend to trade in and out many times a day.

What we could not verify

We could not identify who opened the large short positions, whether Gitcoin itself had any news of its own on Monday, or how much of the Upbit volume came from accounts that had pre-positioned on other exchanges. GTC-specific liquidation totals are not broken out in the data we track.

Quick answers
