Looking at the recent moves in the SUI ecosystem, they still speak volumes. First, the position size is solid—over 108 million SUI tokens, with a market cap approaching $200 million. This scale already demonstrates a long-term bullish attitude towards the ecosystem. Then, regarding the Q4 buyback plan, the action involving 8.8% of circulating shares essentially does two things: first, it reduces the circulating supply; second, it signals to the market that "we believe the price is undervalued."

They also hold $22 million in cash, leaving ample flexibility for subsequent increases or further buybacks. This financial planning approach is quite pragmatic.

On the yield side, it's worth mentioning that the annualized staking return for SUI is only 2.2%, which is significantly lower than similar yields for ETH and SOL, but it’s stable—generating real cash flow every day. For long-term holders, this is no small matter.

Overall, this strategic combination not only caters to asset appreciation expectations but also locks in passive income, which has indeed boosted market sentiment. However, the sustainability depends on whether subsequent buy-in can keep pace and whether SUI’s staking yield can find a competitive edge.
