Bitcoin traded at $66,845 at the time of writing, up 0.42% over the past 24 hours, while price action stayed range-bound. On-chain and flow metrics suggest weaker demand as exchange withdrawals hit 908 addresses and large-holder accumulation appears to stall.

Jimmy Song, co-founder of the nonprofit ProductionReady, said the Bitcoin network needs a "conservative" node client that avoids major code changes unless there is overwhelming community support. He added that ProductionReady expects to restore the 83-byte OP_Return limit to keep node storage costs low, which he linked to decentralization and resilience. Bitcoin Core 30 removed the OP_Return limit in October 2025 by raising it to 100,000 bytes, a move that coincided with growth in Bitcoin Knots usage to 4,746 nodes, or over 21.7% of the network.

Bitcoin has slipped to $66,000 and then confirmed $69,000 as resistance after a bearish retest, setting up conditions that could allow a drop toward $45,000. The roadmap highlights overhead supply zones at $76,000–$79,000 and $88,000–$92,000, while keeping the bearish case active as long as price remains below $69,000. A reclaim of $72,000 is presented as the level that would challenge this downside framework.

Tron posted $81.1 million in trailing 30-day revenue in Q1 2026 while network fees fell to about 15–20 million, their lowest level since 2023.

Coinbase analysts say the crypto market faces elevated risk as President Donald Trump's April 6 deadline on the Iran deal approaches. David Duong warned that a prolonged standoff could raise geopolitical risk premia across energy and broader risk assets, leaving crypto vulnerable into the weekend.

Japan’s 10-year government bond yield climbed to 2.38%–2.39% by early April 2026, the highest level since 1999, as disruption through the Strait of Hormuz pushed energy prices higher and intensified inflation concerns.

The Bank of Japan is set to meet April 27–28, with markets assigning a 60%–70% chance of a rate hike amid rising costs and growth risks.
