Despite the uncertainty of Bitcoin's bullish trend, a key on-chain indicator is the strike price of UTXO age groups, especially the 1-3 month group, which is attracting attention.

The strike price for this group reflects the average price at which recent buyers bought. When Bitcoin's price remains above this level, it shows that the growth momentum is increasing, and new buyers are confident enough to hold on despite the high price. Conversely, if the price falls below this level, the risk of a sell-off increases as participants lose money and may sell off in panic.

Currently, the strike price of the 1-3 month group is located at the $81K area, which acts as an important support zone. The ability to hold this level could determine the direction of the market in the long term.
