Sui (SUI): 22 percent weekly gain ahead of Basecamp on October 7

The token of the layer-1 blockchain Sui (SUI) cost €1.028 on Thursday, October 1, according to CoinGecko. Seven days earlier it was €0.843, a gain of 21.9 percent. Over 30 days SUI is up around 60 percent. With a market capitalisation of around €4.2 billion, Sui sits at number 28 on CoinGecko.

The week is remarkable for two reasons. On September 24 the Phantom wallet, through which many users managed their SUI, ended its support for the network, and the price rose all the same. And on October 7 and 8, Sui Basecamp in Singapore brings the project's most important conference, together with a publicly announced speed test.

The SUI price over the week: from €0.83 to €1.03

The low of the week was €0.828 on Wednesday, September 24, at around 12:00, according to CoinGecko's hourly data, so on the day Phantom pulled out. From there SUI climbed to the weekly high of €1.119 in the night into Sunday, September 28. Since then the price has given back around 8 percent of that, and over the past 24 hours it has barely moved.

The long view helps with placing all this: the all-time high of €5.19 dates from January 4, 2025. Today's price sits around 80 percent below it. The recovery of recent weeks therefore starts from a low base.

The capital in Sui applications is growing again

A second number is moving in the same direction as the price. The capital locked in Sui applications, known as total value locked, stood at $551 million on September 30 according to the data service DefiLlama. At the end of August it was $440 million, a rise of around a quarter in a month.

The distance to the peak remains large, however. In October 2025 the figure stood at $2.64 billion, and today's level is around 79 percent below that. Part of that decline goes back to fallen prices, because the value is measured in dollars, and part to capital withdrawn. September's recovery is therefore a first sign and not yet a return to the old level.

Phantom left Sui on September 24

Phantom announced the step on August 24 and described it as a joint decision with Sui, saying the door remains open for later cooperation. Since September 24 the wallet no longer displays Sui balances, and sending and swapping are no longer possible there. The details are in Phantom's help article, and our report on the announcement is in the piece on the end of Sui support in Phantom.

Important for anyone who missed the date: the tokens are not lost. They sit on the Sui blockchain and depend on the recovery phrase, not on the app. Enter the same phrase in another wallet with Sui support and you see the same addresses and balances. Phantom itself names Slush, the Sui Foundation's wallet, as an alternative.

The price marked its weekly low on the day of the exit and rose again afterwards. A month lay between the announcement on August 24 and it taking effect on September 24. Whether the market priced the step in during that time cannot be read from the price history alone.

Sui Basecamp on October 7 and 8 in Singapore

The in-house conference takes place on October 7 and 8 at Marina Bay Sands in Singapore, alongside the large industry conference TOKEN2049. According to Sui's programme, the focus is on automated payments by AI agents, along with instant settlement, private transactions and stablecoins.

A public speed test is announced for October 7. Kostas Chalkias, co-founder and chief cryptographer of the developer firm Mysten Labs, intends to push the network to its limit live on the main stage. Sui gives its existing record as 6,086,766 transactions per second, reached on July 4, 2026. Figures like that arise under test conditions and say little about everyday life on the network, but they are a date on which a lot of attention rests on Sui.

21Shares pays staking income for its Sui fund

A smaller signal came out of the United States on September 30. The provider 21Shares paid a distribution of $0.052939 per unit for its Sui staking fund TSUI, with September 29 as the ex-date. For investors in Germany the product is as a rule not available to buy, because a key information document is missing. Why that is and which routes exist via Xetra is explained in our piece on the 21Shares distributions.

These levels show the course of the week

The round level of one euro lies directly below the current price, and SUI crossed it in the second half of the week. Below that comes the weekly low at €0.828. On the upside, the weekly high at €1.119 is the first level. These values describe where the price last turned. Price targets they are not, and a conference with announced news can shift the course in either direction.

Buying and holding SUI in Germany

SUI is listed on large exchanges that operate in the EU with an authorisation under the MiCA regulation, among them Coinbase, Kraken, Bitvavo and Bybit EU according to CoinGecko's venue list. An exchange without EU authorisation is an additional risk with a token that rises 60 percent within a month, and it is a risk that can be avoided.

Anyone wanting to hold SUI themselves needs a wallet that explicitly supports the network after Phantom's exit. That is the real lesson of the week: a wallet can drop a network at any time, while the recovery phrase stays valid. Keep it safe and you can move at any time.

On tax in Germany: gains from selling SUI are free of tax after a holding period of one year. Sell earlier and you pay tax on the gain at your personal rate, provided all private disposal gains of the year together reach the threshold of 1,000 euros. Staking rewards are taxable on receipt but do not extend the holding period.

Perpetual futures on SUI exist on many exchanges. Ahead of a conference date with announced news, leverage is especially risky, because expectations can reverse quickly. At five times leverage, the margin is used up by a counter-move of 20 percent.

The risk behind the recovery

Around 4.1 billion of the 10 billion SUI in total are in circulation according to CoinGecko, so 41 percent. The remaining tokens are released under a plan running to 2030, and according to the data service Tokenomist the next release was due on October 1, in favour of the community reserve. Every release brings additional supply that the market has to absorb.

On top of that comes the distance to the peak in locked capital. A price gain of 60 percent in a month with a total value locked that sits around 79 percent below its high shows a change in mood, but not yet a broad return of users. Whether that follows can be checked week by week in DefiLlama's figures.

Sui showed in May 2025 how sensitive a young network can be. Back then the decentralised exchange Cetus, the largest trading venue in the Sui ecosystem, was relieved of around $223 million. A large part of the haul could be frozen, because the network's validators jointly blocked the affected addresses. For those harmed that was good news, and at the same time it showed how much influence a manageable group of validators has over the network. Both belong to the picture when SUI rises as quickly as it has in these weeks.

Sui: Your next three steps

1. Check whether your exchange holds a MiCA authorisation and lists SUI, in the comparison of regulated crypto exchanges.
2. If your SUI were still in Phantom, move them with your recovery phrase into a wallet with Sui support. Suitable apps are in the comparison of software wallets.
3. Record the purchase date and the purchase price so that you can document the one-year holding period. The programmes in the comparison of crypto tax tools help with that.
