Seasoned Bitcoin

 hodlers have hardly spent any coins despite $69,000 all-time highs this year, data shows.

According to the Coin Days Destroyed (CDD) metric from on-chain analytics firm Glassnode, the proportion of coins being spent by old hands remains near record lows.

Strong hands knuckle down throughout 2021

In the latest sign of the conviction of those who invest in and hold Bitcoin over multiple years, CDD remains extremely calm.

The indicator refers to how long each BTC has been dormant each time it moves. This provides an alternative to simple volume measurements to determine market trends. Older coins are thus more “important” than younger ones with a history of active movement.

“Despite a rise over the last few months, the current value is still around historic lows,” Twitter account UTXO Management summarized alongside an imprint of the chart.

The data highlights that since a spike in old hand selling after BTC/USD crossed 2017’s all-time highs of $20,000 last year, strong hands have stayed firm.

Even the run to nearly $70,000 failed to break the trend significantly, and selling still appears to be coming from newer market entrants.

Summer buyers are winter sellers

Another metric, Unchained Capital’s Hodl Waves, confirms this — those coins purchased between three and six months ago now account for the biggest decrease in the overall supply.

This implies that sellers acquired their BTC between June and September this year, the period during which BTC/USD dipped to lows of $30,000.

As Cointelegraph reported, clear distinctions between different groups of hodlers have long been under the microscope.

Even those who entered the market at $20,000 are doubling down, as BTC/USD looks set to end 2021 at around $20,000 higher than at the start of January.

Meanwhile, UTXO Management senior analyst Dylan LeClair last week noted that overall, hodlers are adding to their positions this month.
