Fact Check
The claim is directly and precisely supported by the original Lookonchain X post (id 2084118050450874710), which is the primary source cited by the PANews article. All key figures match: 16,400 BTC, ~$1.04B value, 7 months of dormancy, and transfer to a new wallet. Lookonchain is a widely used on-chain analytics account and references an Arkham explorer address for the wallet, though that explorer page could not be independently fetched (403). Confidence is medium rather than high because the on-chain data itself could not be directly verified in this run, but the well-attributed primary source and corroborating reporting strongly support the claim.

Summary

A Bitcoin whale that had been inactive for four years moved 730 BTC, worth about $46.12 million, to a newly created wallet, according to Onchain Lens. The transfer drew attention because the coins had been accumulated gradually over seven years and then sat untouched in the same address for a long period. Analysts said the activity may be linked to a recently disclosed security vulnerability in the Coldcard hardware wallet, raising the possibility that long-term holders are shifting funds to more secure storage. There is no evidence so far that the bitcoins were sent to a cryptocurrency exchange, leaving it unclear whether the move was meant for sale or simply for custody protection. The transfer follows another large Bitcoin movement from a wallet that had been dormant for about seven months, when 16,400 BTC worth more than $1 billion was shifted to different addresses.
