Could be Roger Ver, but the amounts are massive.
We’ve been watching Bitcoin for 8 years and never seen anything like this,
said the folks at CryptoQuant.

Some interesting alpha regarding the 80,000 BTC transfer that occurred two days ago:
Before the 8 transfers (10K BTC each), someone sent OP_RETURN messages to those wallet addresses saying things like:
"We’ve taken over this wallet"
"Prove ownership by Sept 30"

And linked to a legal site claiming the funds would be considered abandoned if no response by Oct 5, 2025.
The site seems to be from a law firm, but it’s unclear if this approach is even legal.

At first, it looks like maybe a hack — but probably not. Here’s why:
Similar messages went to many dormant wallets, but only these 8 moved BTC.
If someone had the private keys, they could’ve proved it in a more solid way.

Most likely:

Total coincidence.
The real owner saw the messages and moved the coins to be safe.
Or maybe someone’s trying to fake a hack story to avoid proving where the BTC came from.
