https://insights.glassnode.com/the-week-onchain-week-46-2023/Glassnode published a monthly analysis of the onchain that compares supply levels prior to Bitcoin halving, which indicates tightness in Bitcoin supply that has reached historic levels.
Assessing Available Supply
The chart below covers several supply heuristics using 'coin-age' as the main input, measuring the time since a coin was last spent on-chain. Short-Term Holder Supply is currently at multi-year lows of 2.33M BTC, and captures coins up to 155-days old that are statistically the most likely to be spent.
Glassnode developed another supply heuristic that monitors the spending behavior of wallets, classified into Illiquid, Liquid and Highly Liquid buckets. The latter two are shown below which represent wallets that both receive coins and also spend a significant proportion of them.
There is significant overlap between Liquid and Highly Liquid supply and Exchange Balances for obvious reasons. This multi-year downtrend is visible again, suggesting coins are moving out of Exchange wallets and towards more Illiquid wallets with little history of spending.
The analysis is in-depth, so I tried to quote the points above, but you can refer to the link above to read it.
'Available supply' is at historic lows and 'supply storage' This may not be a price prediction signal but more people are preferring to hold Bitcoin.
