Cryptonews reports that spot crypto ETFs have become a major force in the market by absorbing and releasing billions of dollars in crypto assets through their creation and redemption mechanisms. This guide provides a detailed introduction to authorized participants, the creation and redemption cycle, the differences between physical and cash models, and how liquidity directly impacts prices. The design goal of spot ETFs is to align their share price with the price of the underlying crypto assets they hold, avoiding premiums or discounts caused by market volatility. The innovation of ETFs lies in their open-ended share supply, which achieves price tracking through an arbitrage mechanism. Whenever investor demand pushes the ETF's market price above its net asset value, authorized participants purchase the corresponding crypto assets on the market and exchange them for ETF shares, thereby realizing arbitrage. Conversely, when the ETF price falls below net asset value, authorized participants buy ETF shares at a lower price and redeem them to obtain the crypto assets until the price returns to normal. Liquidity data not only reflects market sentiment but is also the visual result of actual trading, making it worthy of close attention from investors. #预测世界杯法国VS摩洛哥 #特朗普宣布美伊停火结束 #GUSD年化升至3.8%
