Why SUI not listed on big CEX like Binance ? What might be the reason behind Sui changing strategy?

Here are several potential reasons why SUI may not be listed on Binance Launchpad, including restrictions on Launchpad product rules and an exclusive agreement between Binance and the project.
The regulations for the SUI IEO differ from past ones in that users can only unlock 1/13 SGD on the day of the sale. The remaining 1/13 will be unlocked at the same time every month. In contrast to Binance’s previous 29 Launchpad projects, none of them have batch unlocking regulations, or additional whitelist sales products tailor-made for project parties. Therefore, the limitations in Launchpad product rules may be a factor in Binance’s inability to select SUI for Launchpad.
A more significant reason is Binance’s exclusive agreement. Whether it’s an ICO or investment project, Binance has exclusive agreements with other trading platforms, which is commonly practiced in the industry. For example, Binance invested in Aptos (APT) and has an exclusive agreement not to work with some platforms. Binance may have requested SUI to agree to the same requirement. Therefore, Binance cannot allow SUI’s IEO to take place on multiple platforms at the same time, while SUI is not open to Binance’s exclusive agreement. This could be why SUI and Binance have not agreed on Launchpad.
Although signing an exclusive agreement with Binance can have its benefits, it can also be a double-edged sword. Aptos (APT), for example, requested major exchanges not to launch perpetual contracts within two weeks, but Binance released APTUSDT 1–25 times perpetual contracts on the first day. While mainstream contract exchanges, such as OKX, Bybit, and others, did not initially announce the release of the perpetual contract.
There is a possibility that SUI requested major exchanges not to allow short-selling of perpetual contracts for a certain period of time, but Binance ignored it. As a result, SUI selected other exchanges to launch on and they may agree to limit the listing of short-selling derivatives.

It is difficult to speculate on when SUI will be listed on Binance, and it may depend on a variety of factors, including when the SUI network is stable and meets Binance’s listing standards.
It is likely that Binance will announce the launch of SUI a few days prior to the mainnet launch. If SUI is launched at this time, Binance may also introduce perpetual contracts simultaneously.
However, it is possible that SUI will not be listed on Binance until the network is stable and meets Binance’s listing requirements. If the popularity of the SUI testnet remains steady before the mainnet launch, SUI tokens will eventually be listed on Binance.
If SUI fails to meet Binance’s listing standards, it may not be listed on the exchange until SUI is unlocked. We should keep an eye on the relevant unlocking schedule.

Why SUI ecology to choose public offering/IEO instead of airdrop?
Sui has announced that they will not be conducting an SUI airdrop plan, but they will be implementing a community access plan instead. This innovative approach means that a significant portion of the value from Sui’s initial offering distribution will be captured by CEX users, such as platform token holders who will receive a portion of the distribution’s value.
Sui’s initial offering distribution will solely be available on CEX and not on the chain. This means that upon the launch of the mainnet, users will need to purchase Sui Tokens on CEX to participate in ecosystem projects. However, this may not be good news for some ecosystem projects as there is a lack of initial offerings on the chain, leading to a considerable loss in users.
In contrast, if L1 conducts an airdrop on the chain, even if more than 80% of the users receive and immediately sell the airdropped tokens, the remaining 20% of addresses holding the tokens will still have invested assets. These on-chain assets can be used as gas fees, interact with various applications, and trade NFTs and FT assets, all of which are crucial for the cold start of early ecosystem projects.
Notably, in light of the lack of initial offering on the chain for early ecosystem projects, MystenLabs and SuiFoundation have created liquidity/TVL plans to assist in providing funds for some infrastructure projects.
