ICX于10月19日失去最后韩元交易市场：Upbit交易关闭前需关注的日期

Please note for ICX holders: October 19, 2026 is the last selling window.

Any investor holding ICX must complete the token sale on its remaining major trading platform before October 19, 2026. At 15:00 Korean time (8:00 am German time), South Korea Exchange Upbit will stop trading ICX to Korean Won (KRW) and delete all outstanding orders in the process. The balances held during this period can still be withdrawn before November 18, 2026. After that, Upbit will end all support for the token, including support for airdrops, wallet upgrades, migration and hard forks.

It should be pointed out that Upbit mainly serves the Korean market and requires users to have a Korean bank account, so it is not a direct trading platform for German investors. Nonetheless, this date is crucial in determining the final realization price for remaining positions in Europe. The Korean won trading pair on Upbit is ICX's last large trading market globally and will disappear about ten weeks before the complete shutdown of the ICON blockchain.

The specific event that occurred in Upbit on October 19

"Deliting" refers to the removal of cryptocurrency assets from the exchange: trading pairs will disappear from the list and purchase orders will no longer be available thereafter. Upbit's phased removal of ICX is divided into two steps, the first step taking place on October 19.

At the close of the day, the exchange will uniformly cancel all remaining orders in the pending order book based on its announcement. This means that a sell order originally held well above the market price will not be sold but will be revoked. Only in the second stage four weeks later will the withdrawal window close. This process is consistent with convention and contains more critical information for holders: between October 19 and November 18, balances can be transferred out although no longer traded. The date was first disclosed in a South Korean trade publication report on September 18.

Reason for Upbit to stop trading: Replay Attack and Warning List

Upbit explained the removal based on unresolved security risks. The background is an incident that occurred on the ICON chain at the end of August. In a "replay attack", a validly signed transaction was committed again, causing the same instruction to be executed multiple times, even though the instruction was authorized only once.

According to existing reports, a total of 1,492 such signed withdrawal messages were reused on August 27. This resulted in the release of 119.9 million ICXs and 531,600 bnUSDs, and the status on the chain was suspended for about 25 hours. On August 28, Upbit placed the token on the warning list and decided to terminate trading support after further review. Since Upbit's announcement page is not freely accessible outside South Korea, the dates and reasons are mainly based on reports from the South Korean and international media industries rather than the exchange's official page itself.

There is only one market left: of Upbit's 865 trading pairs, only 18 carry warning signs. As of October 9, these 18 trading pairs are almost exactly consistent with the current removal and review queues: in addition to ICX, they also include BLAST, EGLD, MANTRA, RVN, SOPH and ZIL. Among this group, ICX is the only asset on Upbit with a single trading pair left. Its previous trading pairs with Bitcoin and USDT no longer exist. EGLD, MANTRA, RVN, and BLAST still have two to three affected pairs each; for ICX, with the disappearance of the Korean won trading pair, support for the entire platform also ends.

Nearly half of the world's ICX trading volume via Upbit

liquidity describes the market's ability to absorb orders without causing significant price concessions; the thinner the liquidity, the higher the cost of selling. For ICX, its liquidity scale is small and it relies heavily on a single location.

On Thursday, South Korean won trading pairs on Upbit traded approximately 501 million won, the price was 19.6 won, and the volume was 25.8 million ICXs. Converted into U.S. dollars, the amount ranges from US$348,000 to US$373,000, depending on the official exchange rate or the global market price of the token. During the same period, the average daily total turnover of all platforms around the world was approximately US$776,000. As a result, Upbit alone bears 45% to 48% of all ICX transactions. The market value of the token is approximately US$14.9 million.

This order of magnitude is the core significance of the date. When nearly half of the trading volume disappears in one day, it is difficult to reallocate the rest to other platforms, resulting in significant thinning of the remaining market. Selling a larger position after that means your order will drive price fluctuations.

Premium about 8%: ICX prices in the Korean market are higher than in the global market

The second effect is easily ignored when looking at a single price. On Thursday, the price of an ICX on Upbit was 19.6 won. At official exchange rates, this is approximately 1.46 cents, while the token trades for approximately 1.35 cents in global markets. As a result, the Korean market paid a premium of about 8% for the same token.

Such premiums have been known in South Korea for many years because the flow of capital between South Korea and international markets is not as smooth as price differences suggest. Regarding assessing the impact of this removal, the consequences are as follows: The average ICX price displayed on the current price page includes a portion of South Korea's demand share purchased at a higher price. If the market disappears, this premium demand will disappear with it.

Withdrawal of coins before November 18: Upbit's second deadline

Upbit的交易关闭与提币关闭之间有四周的时间差。在此期间，任何仍持有ICX在韩国账户中的用户可以将余额发送到自己的地址或其他交易所，但不能再进行交易。2026年11月18日之后，Upbit还将明确停止处理该代币的空投、钱包升级、迁移和硬分叉。

这一点在ICX案例中并非无关紧要。ICX转换为SODA的过程（整个剩余供应量都依赖于此）在技术上正是一种迁移过程。停止迁移支持的交易所实际上剥夺了持有者通过账户处理互换的选项。

截至12月31日的ICX截止日期日历

Upbit的日期并非孤立存在。对于欧洲ICX持有者来说，年底前有多个有期限的截止点排队等候，其中大多数已经过去或即将来临：

• 2026年10月2日：Bitvavo关闭了ICX的存款、交易和提币。根据时间表，此后留在账户中的任何余额最迟将于10月12日自动兑换为欧元。详情见我们关于Bitvavo强制转换的报告。
• 2026年9月30日和10月3日：OKX首先结束了欧元交易对，随后是USDT交易对。根据我们关于OKX下架的文章细节，该交易所接受提币直至2026年12月23日。
• 2026年10月19日和11月18日：Upbit的交易关闭和提币关闭。
• 2026年12月31日：ICON区块链将关闭，同时ICX转换为SODA的选项也结束。

Binance已于今年9月早些时候将ICX撤出现货交易。如果有人怀疑余额仍在其中，可查阅我们关于Binance下架的文章以了解当时的日期序列；然而，文中提到的11月提币日期仅来自一个次要来源，应持谨慎态度。如有疑虑，请直接检查账户中的提币窗口。

自9月30日起成为单行道：回归ICX的道路已关闭

“迁移”是指旧代币与新代币的互换：ICX被提取，SODA被发行。ICON基金会早在5月就设定了相关日期并发布在其项目页面上。这两个截止点对持有者的意义已在8月我们关于ICON区块链关闭前两个截止日期的概述中梳理清楚。自9月30日起，互换只能单向运行；此后已排除将SODA转换回ICX的可能性。2026年12月31日，链将永久停止运行，仅保留一个用于查询旧交易的存档。

这意味着到年底，ICX余额只有两种状态：已互换，或在关闭链上归零。未互换部分的大小已在9月初由cryptoticker.io通过对其自身计数的两条链确立：当时，仍有11.09亿枚ICX停留在ICON链上，且没有公开的迁移进度指标。目前没有更新的可靠数据。

交易所或自有钱包：谁执行迁移？

“自我托管”（Self-custody）意味着硬币的密钥由持有者保管，而非交易所。对于ICX迁移而言，这种区别决定了谁必须采取行动。

如果余额位于自行执行迁移的交易所，则由平台处理互换并贷记SODA。多家平台已完成此操作，并在此过程中自动将客户余额转换。相比之下，如果余额位于私人钱包中，它不会自动迁移：持有者必须通过项目的官方门户启动互换，且12月31日的截止日期严格适用。决定时间表的关键不是12月31日，而是你自己的交易所停止支持的那一天。

模仿门户网站往往会在这种迁移期间激增。请仅通过官方项目地址打开互换页面，切勿输入助记词；真正的迁移门户请求的是钱包签名，而不是单词列表。

持有期与税务：出售、强制转换与迁移的区别

“持有期”是指在德国，加密货币私人出售收益免税的时间跨度；根据德国《收入税法》第23条，这一期限为一年。在这一年内，收益需纳税，但每年所有私人处置的总和有一个门槛。

There are currently three routes running in parallel and are not the same in terms of tax treatment. Self-sale on an exchange is a clear disposal with a date and a yield. Forced conversion (exchanges convert remaining balances into euros without requiring orders) is also an economic sale, but it lacks your subjective decision about timing; it also triggers a tax event. In contrast, the conversion of ICX to SODA is legally controversial: whether swaps during the project migration process count as a disposal of old tokens or a continuation of the same investment has not yet been finalized, and the answer determines whether the holding period starts over.

In practice: Record the time of each event, the number of tokens involved, and the value generated. For positions held since 2021 or earlier, the issue of whether the holding period will restart may be more decisive than the price itself. For large positions or unknown acquisition history, it is recommended to consult a tax consultant rather than rely on rules of thumb.

Reasons against and reasons for fast sales

Market mechanisms support rapid exit. As the Korean won pairs disappeared, nearly half of the trading volume disappeared, and the premium of about 8% in the Korean market disappeared. No matter how you plan to sell, the longer you wait, the more you will sell in a less liquid market. In addition, with a market value of just under $15 million, even medium-sized orders leave a visible mark on the price.

The reasons for opposing a hasty sale are tax issues and the size of the money. At 1.35 cents per token, a position value of 10,000 ICXs is approximately US$135; trading and withdrawal fees may eat up a significant portion. If you choose to migrate rather than sell, you retain the position in the new successor project, but also assume its risk. And the risks are real: a project to shut down its own blockchain, and a token removed from the largest platform because of unresolved security issues, are warning signs. At this value scale, complete loss is possible, no matter which route you take.

This article cannot provide advice because the correct answer depends on the purchase price, holding period, position size, and your evaluation of the successor project itself. What it provides is a calendar: After October 19, the cost of executing every decision will increase, and after December 31, one decision will be completely impossible to achieve.

ICX: Four next deadlines were decided on October 19.

Three steps were taken to sort out the situation. The first step would only take a few minutes:

1. Determine the balance and its location. Check each account and wallet to find out where the ICX is still stored, and record the applicable expiration dates for each location. If the balance is on an exchange that has removed it, the withdrawal deadline is key. Which platforms are suitable for transfer, please refer to our Cryptocurrency Exchange Comparison.
2. Decide before October 19, not after. 出售或迁移是两条路线；两者在交易关闭前执行都比之后更便宜。从自我托管中迁移需要访问密钥和网络费用的少量储备。适合的设备请参阅硬件钱包比较。
3. 记录每一个事件。日期、代币数量和每次出售、强制转换及互换的价值都应记录在你自己的账目中，趁交易所仍在显示这些数据时。账户关闭后，获取证据将非常费力。我们关于加密税务软件和投资组合跟踪器的概览中的工具可帮助收集这些信息。
