According to BlockBeats, data from Coinglass on April 28 reveals that the Grayscale Ethereum (ETH) Trust (ETHE) and Ethereum Classic (ETC) Trust are currently experiencing negative premium rates of 24.78% and 38.72% respectively. This is a significant increase from previous reports, which showed that the Grayscale ETHE negative premium rate had narrowed to 8.17% on March 9. The current negative premium rates indicate a decrease in demand for these trusts, which could potentially impact their market value. However, it is important to note that these rates are subject to change based on market conditions and investor sentiment.
