A wallet that had been dormant for 13 years and another for 12 years suddenly transferred BTC to the same receiving address almost simultaneously. I was honestly stunned when I saw this: two funds that hadn’t moved in so long acted at the same time—it’s highly likely they belong to the same person. [1ECHiGyhvCifeuhdNQJZGD3QeiizGAJCcb](https://((arkm.com))/explorer/address/1ECHiGyhvCifeuhdNQJZGD3QeiizGAJCcb) transferred approximately 167.84 BTC; [12txLhfB9TpZ4LrjF21B9Jj3eJ7J7coUm3](https://((arkm.com))/explorer/address/12txLhfB9TpZ4LrjF21B9Jj3eJ7J7coUm3) transferred approximately 248.85 BTC. That’s a total of about 416.69 BTC, worth roughly $33.82 million at the time the monitoring post was published. Back when these coins entered the two wallets, they were worth a combined total of about $105,000. From just over $100K to more than $33 million—that’s already jaw-dropping. But what’s even crazier is that this wasn’t just one old wallet waking up; it was two wallets, dormant for different lengths of time, making moves at the same moment. On-chain transfers can’t prove they belong to the same person, and it doesn’t mean they’ve been sold. But seeing them move together after more than a decade, I can’t help but wonder: who’s been holding onto these coins all this time?
