- Whale wallet bc1qpt moved its full 16,400 Bitcoin (~$1 billion) to a new address on Monday after seven months of inactivity, according to blockchain analytics platform Lookonchain
- Daily crypto trading activity across 44 spot exchanges fell to $15 billion last week — the lowest level of 2026 — per data from Kaiko shared by The Kobeissi Letter
- The Kobeissi Letter called the drop a -70% decline from January peak levels, writing in a Tuesday X post that "crypto market liquidity is drying up"
- Glassnode found that nearly 10% of Bitcoin's supply is "structurally unsafe" from a potential quantum computing breakthrough
- Blockstream CEO Adam Back said in November 2025 that Bitcoin faces no meaningful quantum threat for at least the next 20 to 40 years
- Bernstein analysts wrote in an April report that Bitcoin has about three to five years to prepare for a post-quantum security upgrade
- Bitfinex analysts called the three-to-four-year quantum timeline "premature," arguing practical quantum threats capable of breaking Bitcoin's cryptography remain unlikely within the next decade
Why it matters: A $1 billion whale transfer landing on the same week trading volume hit a 2026 low shows how thin liquidity has become — a single dormant wallet's reactivation can move the needle — while the unresolved quantum debate leaves roughly 10% of Bitcoin supply exposed if Bernstein's 3-5 year timeline proves closer to reality than Blockstream's 20-40 year estimate.
