Since Easter’s price climb thrust bitcoin to fresh highs, a wave of once-silent coins has begun to stir. In just the past few days, 790.97 BTC—now valued at about $74.10 million—have left hibernation after years of inertia.

Slumbering Bitcoin Cohort Awakens After Easter Rally

As BTC breezed past $93,000, a wallet born on Sept. 14, 2012—nearly 13 years old—finally moved its 242 BTC for the first time at block height 893,589. The trove, now assessed at $22.6 million, journeyed from a classic P2PKH (Pay-to-Public-Key-Hash) address to a modern Bech32 P2WPKH (Pay-to-Witness-Public-Key-Hash) destination.

Back when the owner acquired the hoard, it was valued at just $253.40, translating into an eye-watering 8,923,480% appreciation since then. Yesterday, eight wallets dating back to February and March 2013 awakened, each dispatching 25 BTC, for an aggregate 200 BTC now worth $18.7 million—their first activity in more than a dozen years.

Data gathered by btcparser.com shows the coins departed from eight individual and legacy P2PKH addresses. Similarly to the 2012 transfer, the full allocation converged in a fresh Bech32 P2WPKH wallet. Momentum for reanimated bitcoin became a lot more prominent on April 21, when four addresses created in June 2017 sent 126.96 BTC across four transactions.

On Tuesday, April 22, ahead of the 2013 wallets’ activity, a 2016-era address born in October dispatched 83 BTC at block height 893,448. In the same block, another October 2016 wallet released an additional 70 BTC. Such stirrings are hardly uncommon; dormant BTC addresses tend to grow livelier during price booms.

Whether the coins will hit exchanges or merely relocate to updated formats is unknown. Should bitcoin’s rally persist, it seems as though plenty more slumbering coins will soon stretch their legs.
