Alex Thorn, Galaxy Digital's head of firmwide research, expects Bitcoin to reach $250,000 by the end of 2027. He cautioned that 2026 is hard to forecast and said options markets currently assign equal odds of $50,000 or $250,000 by the end of next year, reflecting heightened near‑term uncertainty.

Wang Chun, co-founder of Bitcoin mining pool F2Pool, recounted a 2024 incident where he reportedly sent 500 BTC into a wallet he believed was compromised to test if it was under hacker surveillance, resulting in the loss of 490 BTC. He shared this story after a separate December 20 phishing case in which a user mistakenly transferred about 50 million USDT in an address poisoning attack and is now working with law enforcement to recover the funds. The Ethereum Community Foundation has urged wallets and explorers to stop truncating addresses with dots, arguing that this interface choice unnecessarily increases the risk of such scams.

Artificial intelligence-driven growth in U.S. data centers is sharply increasing electricity demand and pushing utilities into one of their largest capital spending and borrowing cycles in decades.

On 21 December 2025, Bitcoin was trading near $88,296 and on course to finish the year with a negative yearly candle. Long-term price records indicate the asset has never logged two consecutive red yearly closes, with past down years such as 2014, 2018, and 2022 each followed by recoveries. If this pattern persists, the current setback could again precede a rebound after 2025, although future performance remains uncertain.
