Bitcoin Wallet's Mysterious 'Round Trip' Raises Questions About Ownership and Intent

In March, an almost-dead Bitcoin wallet suddenly resurfaced and moved about $1 million worth of BTC through a large centralized custodian. The same amount was sent back three weeks later, minus only a tiny difference of around $3. This 'round trip' has left researchers puzzled.

Chainalysis analysis suggests that five separate wallets involved in the burn show 'strong indicators of common ownership', implying that the same party controlled these addresses at some point. Most of the funds can be traced back to Mt. Gox-era origins, suggesting an early Bitcoin holder connection.

The 'round trip' doesn't fit a simple trading explanation, as the coins did not just reappear somewhere else, they returned to the same address that had sent them to the custodian. The use of round numbers may align with custodial withdrawal limits.
