A Polymarket trader has reportedly earned $320,000 by accurately predicting U.S. President Joe Biden's final pardons, according to NS3.AI. The trader utilized two linked wallets, identified by Bubblemaps, to place successful bets on four last-minute pardons. Additionally, the trader had previously wagered that Biden would pardon Hunter Biden. This discovery has intensified scrutiny over the timing of political bets, as CFTC Chair Mike Selig is questioned by Congress about the potential need for investigations into such trades.

Public crypto miners have sold over 32,000 BTC in the first quarter of 2026, surpassing their total sales for the entire year of 2025. According to NS3.AI, data from Hashrate Index indicates that the hashprice stands at approximately $33 per PH/s per day, which is below the $35 breakeven point for many miners. Additionally, CryptoQuant data reveals that the amount of BTC held by miners has decreased from over 1.86 million at the end of 2023 to about 1.8 million at the time of publication.

Publicly traded Bitcoin mining companies have sold more Bitcoin (BTC) in the first quarter of 2026 than in all four quarters of 2025, reflecting tightening business conditions within the mining industry. According to Cointelegraph, these companies, including MARA, CleanSpark, Riot, Cango, Core Scientific, and Bitdeer, collectively sold over 32,000 BTC in Q1 2026, as reported by TheEnergyMag. This figure surpasses the 20,000 BTC sold in Q2 2022 during the crypto bear market triggered by the Terra-Luna ecosystem collapse, setting a new record for BTC miner sales in a single quarter, according to TheMinerMag. The increased sales occur as hashprice, a critical metric for miner profitability that represents computing cost, remains at record low levels under $35 per petahash/second per day (PH/s), based on data from Hashrate Index. This $35 PH/s level is the breakeven point for many Bitcoin miners, especially those operating older mining machines. The current hashprice of approximately $33 PH/s per day places about 20% of the mining industry in unprofitable territory. Hashprice for BTC miners has been declining since July 2025 and now sits at about $33 PH/s per day, according to Hashrate Index. The mining industry faces increased competition due to a rising hashrate, reduced block rewards, and macroeconomic challenges. The Bitcoin Miner Reserve, which tracks all BTC held by miners, has been gradually decreasing since 2023, as noted by CryptoQuant. Bitcoin miners collectively held over 1.86 million BTC at the end of 2023 but currently hold about 1.8 million BTC. Miners periodically sell portions of their BTC to cover operating expenses, but lower crypto prices and rising energy costs have forced some to offload coins they would have held in their corporate treasuries. Asset manager CoinShares anticipates further capitulation among higher-cost operators in the first half of 2026 unless BTC's price recovers significantly. In contrast to the miners' selling, Bitcoin treasury companies like Strategy continue to acquire BTC. Michael Saylor, co-founder of the largest Bitcoin treasury company, indicated earlier this week that Strategy is purchasing more BTC as the price retreats from a local high of over $73,000 reached this week. "Think bigger," Saylor remarked on Sunday, sharing Strategy's BTC purchase history chart, which has become synonymous with imminent BTC acquisitions.

Lido DAO has sanctioned a $20 million buyback initiative, resulting in a 30% increase in LDO's value over the past month, even as other major DeFi tokens experienced declines. According to NS3.AI, the approved plan allows the DAO to utilize up to 10,000 stETH, approximately valued at $23 million, for the repurchase of LDO tokens. CoinGecko data indicates that LDO was trading at $0.42, marking a 12% rise in the last 24 hours.

On April 17, ECB Governing Council member Nagel stated that releasing clear signals about future interest rate paths before this month's rate decision would be a mistake. According to Jin10, he mentioned that policymakers currently lack sufficient information to determine whether the surge in energy costs will keep inflation high in the long term, which will dictate whether a policy response is necessary. "We need to maintain flexibility, and it is inappropriate to assert that rates will move in a certain direction now. I am not ready to make a commitment in advance," Nagel said. Insiders revealed that the ECB is inclined to keep rates unchanged at this meeting, but in the rapidly changing environment, a rate hike is not ruled out. Nagel noted that Germany's economy performed reasonably well at the beginning of the year, but momentum weakened due to the impact of the Iran war, with economic growth expected to be 0.3 percentage points lower than previously forecast this year. He also warned that investor sentiment is overly optimistic. "The current market is relatively optimistic because of the widespread assumption that lasting peace will be achieved in the Middle East and energy prices will fall," he said. "The central bank's duty is to ensure that if this scenario does not materialize, it will not have spillover effects on financial stability."

More than a dozen major U.S. law firms have issued warnings to their clients regarding the use of AI chatbots in legal discussions. According to NS3.AI, these firms caution that engaging in legal conversations with AI tools may compromise attorney-client privilege. This advisory comes in the wake of a February ruling by Judge Jed Rakoff in New York, which allowed prosecutors to use a fraud defendant's Claude chatbot interactions and 31 AI-generated defense documents as evidence in court.
