A Series Of 200 “Sleepy Bitcoins” From 2010 Worth $4.27 Million Moved On Friday

With the price of bitcoin holding above the $21,000 per unit range, four bitcoin block rewards mined in 2010 were spent for the first time in over 11 years. The four block rewards were mined between September and October 2010 and the 200 bitcoins worth $4.27 million were transferred to an unknown wallet.

4 consecutive blocks of rewards spent on June 24, data suggests spending was executed by a single entity

A large number of so-called “sleeping bitcoins” woke up from sleep as four block rewards were spent at a block height of 742,183. The old coins spent on Friday were block rewards mined on the 15th, 16th, October 26 and 29, 2010. During this period, bitcoin miners received 50 BTC for each block found, as opposed to the 6.25 BTC per block reward miners get today. .

The moved block rewards came from four addresses which include “18cxWU”, “1BJmWW”, “1FVVcE” and “1Hdo8D”. The 2010 spending was captured by blockchain parser btcparser.com and in all four addresses the owner did not spend the associated bitcoin cash (BCH) and bitcoinsv (BSV) as these coins remain inactive.


Blockchain explorers show that the 200 blank bitcoins were sent to a single address (bc1q92) and the coins remain dormant at the time of writing. A consecutive number of 2010 block rewards spent in the same block suggests that a single entity was likely the owner of the block rewards. The bitcoins mined in 2010 over a two-month period (September and October) also suggest that the expenditures were executed by a single entity.

Transfers had low privacy ratings, ‘Sleeping Bitcoin’ chain spending from 2010 slowed

It appears that the addresses have been scanned and the transactions have a very low privacy rating for various reasons. Blockchair.com’s privacy meter indicates that the final consolidation in bc1q92 had a privacy score of 0 out of 100. The transactions contained vulnerabilities such as matching addresses, joint spend, and the same address is used in multiple entries.

There haven’t been many block reward spending streaks in 2010 since 2010’s mega-whale appeared months ago in March. The mega whale of 2010 usually spent strings of 20 block rewards of that year in one go. Prior to the round of four 2010 block grants spent, a week ago the address “1Li8RF” spent 50 virgin bitcoins and “1LNqDK” spent 50 BTC 2010 about a month ago.
