98% ETH Supply Is Currently in Profit
Amid the massive 60% ETH price rally over the past month, the cryptocurrency’s market cap climbed above $500 billion, while overtaking giants like Netflix.
Following the recent rally, about 98% of ETH holders are in profit, which further raises the chances of profit-taking.
On-chain analytics firm Glassnode reported that Ethereum’s “Percent Supply in Profit” metric exceeded 98% on Thursday, marking its highest level in two years.
The indicator tracks the proportion of ETH coins currently valued above their last on-chain transaction price. Coins are considered “in profit” when the market price is higher than their previous transaction price and “in loss” when it is lower.

Historically, levels above 95% indicate an overheated market nearing a local peak, as the majority of investors sit on unrealized gains. This increases the likelihood of profit-taking.
I keep saying this, your time to buy $ETH isn't right now, that was earlier.
I'd prefer to wait for a strong correction to be chasing a position in $ETH.
Areas to monitor:
$4.2K
$3.8KTargets after that?
Higher than $5K I would assume. pic.twitter.com/vxlLUUNmPk

So far, ETH treasury firms like Bitmine Technologies have supported the upside rally amid heavy accumulation over the past two months. The coming weeks will reveal whether whales are using this demand as an opportunity to exit their positions.
