Bitcoin is moving into one of its most important on-chain resistance areas, with Glassnode data showing that about 623,000 BTC last changed hands near $63,111. That concentration now stands as the largest realized price cluster above the market and has turned the $63,000 region into a major test for bulls.
Ali Martinez said many holders who bought near that level may look to sell once price returns to their entry. That would increase overhead supply right where Bitcoin is trying to break higher. He also pointed to rising global uncertainty as a factor that could push investors to cut exposure to risk assets.
URPD data highlights where holders may react
The analysis is based on Glassnode’s UTXO Realized Price Distribution, or URPD. Rather than tracking order books, the metric maps the prices at which coins last moved on-chain. Those levels often act as cost-basis clusters, and when price revisits them, holder behavior can become more aggressive.
In this case, the cluster around $63,111 is the largest currently visible on the network. That makes it a natural resistance zone, since holders who sat through previous declines may decide to exit once they are back near breakeven. If buyers fail to absorb that supply, the recovery could stall at this level.
More resistance sits above the current range
Even if Bitcoin clears the first barrier, Glassnode’s chart shows more supply overhead. Another notable cluster appears near $66,898, followed by a separate concentration around $69,422. If the rebound extends, those levels could also attract profit-taking.
So the issue is not only whether Bitcoin can touch $63,000. The market is watching whether it can push through the largest supply cluster and hold that move. A clean breakout would remove one of the biggest overhead zones now visible in the on-chain data.
Loss of $59,000 could shift attention to lower support bands
Martinez said the downside picture becomes more serious if Bitcoin fails at $63,000 and then loses support near $59,000. Based on Glassnode’s transaction history, the next major support area sits around $46,700, where about 115,000 BTC previously moved.
Below that, a larger accumulation zone appears near $37,870, representing roughly 206,000 BTC. For now, Bitcoin’s reaction near $63,000 remains the main focus. A breakout would clear a major overhead supply zone; another rejection would put lower historical support levels back in view.
