ChainCatcher news, according to Jinshi Data reports, the Hong Kong Stock Exchange will implement a new stock trading fee structure starting today (30th), completely breaking the previous limits of a minimum of 2 HKD and a maximum of 100 HKD. "This adjustment is related to the Hong Kong market's policy to lower the minimum tick size (the smallest price movement unit for buying and selling stocks). Under the new standard, the cost for investors making small trades will significantly decrease," industry insiders stated. Specifically, in the past, due to the existence of a minimum fee limit, the trading costs for small transactions were relatively high.For example, for a transaction of 1,000 HKD, the minimum fee was 2 HKD, resulting in a fee ratio of up to 0.2%. After the adjustment, the fee ratio is 0.0042%, which is 0.042 HKD, significantly reducing costs. At the same time, the minimum and maximum fee limits have been removed, allowing institutional investors to calculate trading costs more accurately, optimize trading strategies, and better control costs during large-scale transactions. In addition, under the new regulations, fees will still be charged on both the buy and sell sides.

ChainCatcher news, Trading Strategy co-founder Mikko Ohtamaa criticized Polygon for using user-bridged USDC deposits for funding markets (such as Morpho), believing this practice poses multiple risks:Undermining the illusion of self-custody: Although the Polygon bridge is controlled by a multi-signature wallet, this operation breaks users' trust in self-custody.Attracting regulatory scrutiny: The movement of billions of dollars could attract significant attention from regulators and the media.Lack of user choice: Currently, users cannot choose whether to participate in this mechanism, resulting in a lack of transparency.Double counting issue: The bridged USDC is used for lending services on Polygon while also being utilized in Morpho on the mainnet.He suggested that Polygon explore more transparent methods, such as launching an independent bridging service that allows users to choose to convert USDC into "Polygon yield-bearing USDC." Additionally, he mentioned that Circle has launched a non-bridged version of USDC on Polygon, but due to its late introduction and incompatibility with the bridged version of USDC, it has not gained widespread adoption.
