On April 19, Alcoa Corporation is set to finalize a deal with Bitcoin mining company NYDIG to sell its idle Massena East aluminum smelter located in New York State, with completion expected by mid-year. The facility has been inactive since 2014 and includes supporting infrastructure such as a substation, transmission lines, and high-capacity grid access. It can utilize hydroelectric resources provided by the New York Power Authority, making it attractive to Bitcoin mining and data center operators. Reports indicate that some retired industrial sites in the U.S. are being repurposed for Bitcoin mining, artificial intelligence, and high-performance computing facilities.

On April 19, Spark's Strategic Director monetsupply.eth posted on platform X that as the stablecoin market begins to lack liquidity, the situation is entering a more dangerous phase. I believe that approximately 16.5% of the ETH market is supported by rsETH, and if the loans backed by rsETH incur losses distributed across the mainnet and external chains, there may be a 10% to 15% reduction in emode, leaving 2% to 3% reduction for ETH suppliers to smooth out the umbrella structure. ETH suppliers naturally tend to exit as quickly as possible to avoid this risk, thus utilization is locked at 100%, and borrowing rates are insufficient to incentivize the repayment of unrelated LST cycles (wstETH, weETH) to release liquidity. Due to the inability to withdraw ETH, users who borrow stablecoins like USDT and use ETH as collateral cannot close their positions even when stablecoin borrowing rates rise, which cuts off the typical incentive mechanisms that maintain market health. Currently, there are two unhealthy incentives leading to market utilization being locked at 100%: 1) ETH holders cannot close their positions to maintain a healthy LTV, and liquidators cannot atomically withdraw or sell collateral, which could lead to bad debts if ETHUSD prices fall. 2) Users supplying USDT to exit their holdings tend to maximize borrowing of other stablecoins, as this position is currently generating positive returns (temporarily), making the exit cost low; if conditions worsen, they can at least recover 75% of the position value. The bottom line is that these pooled/re-staked lending markets must maintain liquidity at all costs to operate normally. The recent weakening of slope2 against Aave's maximum borrowing rates is having a negative impact and significantly increasing the risk of cascading market failures.

On April 19, Al Jazeera reported that two Pakistani security sources indicated that negotiations between the United States and Iran are likely to take place before Friday. The sources based their assessment on several factors: two US heavy transport aircraft (C-17 Globemaster) have landed at Nur Khan Air Base in Rawalpindi, located near Pakistan's capital, Islamabad. Additionally, the road from the airport to the Red Zone in Islamabad has been temporarily closed, suggesting that security measures have been heightened. The Serena Hotel and Marriott Hotel in Islamabad are evacuating guests and are not accepting new bookings before Friday. The Serena Hotel was the venue for the first round of US-Iran negotiations on April 11. According to monitoring by PolyBeats, the probability of the 'next round of US-Iran diplomatic meetings' occurring before the 22nd (next Wednesday) is 52%, and the probability before the 30th is as high as 73%.

On April 19, on-chain analyst Murphy noted that after Bitcoin (BTC) reached $78,000, the 24-hour average realized profit the following day was $39.15 million, which is lower compared to when BTC hit $76,000 on April 14. The divergence between 'price action' and 'realized profit' typically indicates that the demand side can no longer sustain the concentration of profit-taking, leading to a decline in upward momentum, similar to the situations observed on January 7 and January 14. Additionally, the reduced trading volume over the weekend may also be a contributing factor. If the divergence between 'price' and 'profit' is primarily due to the demand side's inability to sustain further profit-taking, it can be reasonably concluded that the rebound has peaked. However, if the main reason is the decreased market activity over the weekend, further observation will be necessary in the upcoming trading days.
