Upbit New Coin Listings: Why There's a "5-Minute Limit-Order Buy Restriction"

If you've ever tried to buy a newly listed coin on Upbit, you may have wondered why you can't buy during the first 5 minutes. When I started, I'd just sit there waiting, thinking, "Why isn't this working?"

On top of that, even after the 5 minutes pass, you can only buy with limit orders for the first hour after listing, which also caught me off guard. It turns out there are good reasons for both. For anyone who's been just as curious as I was, I'll go through them one by one.

1. Why You Can't Buy During the First 5 Minutes After Listing

When a new coin is listed on Upbit, lots of investors tend to rush in. Frustratingly, you can't buy for the first 5 minutes. The reason is to secure liquidity and stabilize the price.

With new coins listed on Upbit, supply can be thin right after listing. So, for the first 5 minutes, only sell orders are opened, giving enough orders time to build up on the order book. In other words, sellers' price levels take shape during those first 5 minutes, and buyers can then trade more safely afterward.

2. Why Only Limit Buy Orders Are Allowed

Even after the buy restriction is lifted, you can only place limit buy orders for the first hour after listing, which can feel a bit inconvenient. But there's a reason for this too.

The biggest reason is to prevent excessive volatility. Newly listed coins usually see trading volume explode, which leads to big price swings. If market buy orders were allowed, there'd be a high chance of the price spiking in an instant.

Limit buy orders, on the other hand, execute at the price each investor sets, so they help prevent distortions caused by excessive price surges.

3. Why Gains Skyrocket After Listing

New coins listed on Upbit tend to rise sharply early on. But the percentage gain shown at that point can actually be a trap.

That's because after Upbit announces a listing, the coin usually rallies hard on overseas exchanges like Binance or OKX, while Upbit lists the new coin based on the price from an earlier point in time.

That's why the gain figure alone can show tens or even hundreds of percent without much actual trading after listing. Of course, there are also cases where heavy buying pressure genuinely drives the price up, but in those cases it's usually accompanied by substantial trading volume.

4. Overseas "Bottari" Trading and Kimchi Premium Opportunities

For new coins listed on Upbit, deposits often open on chains like Ethereum or Solana before trading begins. Some traders see this as an opportunity, buying the coin on overseas exchanges and using bottari (cross-exchange transfer arbitrage) and hedging to trade the kimchi premium.

In practice, right after listing there can be temporary price differences between exchanges, and the gap between spot and futures can widen along the way. It's not a strategy beginners can pull off easily, but there are people who do this professionally.

Wrapping Up

That covers why buy orders are restricted for the first 5 minutes when a new coin is listed on Upbit. In the end, it comes down to supplying liquidity and protecting investors. For the same reasons, only limit orders can be submitted for the first hour after listing.

Also keep in mind that for about 5 minutes after trading support begins, you can't place sell orders at prices 10% or more below the previous day's closing price. I hope big bro Seok-woo keeps bringing us plenty of good, profitable listings. Thank you.
