During the 30-minute tracking, the top gainer has shifted from $LAB to $AT.

The last top was $LAB, with a 24-hour increase of 51.08%, and the current top $AT is 35.77%, indicating that the market's strongest focus has rotated, and the previously hot target no longer holds the first place.
The most obvious change is the disparity in capital scale.
Open interest (OI) dropped from $103.9M to $10.9M, showing that this time $AT 's position size is significantly lighter, making it easier for new positions to push the price higher and easier for concentrated liquidations to amplify volatility.
However, $AT 's own OI is not weak.
The 24-hour OI increased by 44.2%, and the 1-hour OI increased by 12.4%, indicating that it’s not just spot price rallying, but that contract positions are continuing to flow in.
Funding rates decreased from 0.0622% to 0.005%, showing that the crowding of longs is much lower than last time $LAB , and the short-term cost to force longs is not as exaggerated.
Taker buy-in increased from 1.05 to 1.12, indicating that active buy orders still dominate.
Retail long positions increased from 24% to 41%, showing that the bullish sentiment is more evident than last time, but not yet at an extreme consensus.
The key counter-evidence lies in two points.
If OI continues to rise but the price cannot break through the high near 0.17175, it suggests that new positions may start turning into high-level opposition.
If the funding rate rapidly rises again, and the long-short ratio continues to tilt toward longs, it indicates that crowding will increase, and the quality of trend continuation may be compromised.
The core of this round of $AT is not the largest increase but the acceleration of light OI entering the market.
The top rotation has already occurred, and the next step is to verify whether the high near 0.17175 is a handover relay or the first stress test of new positions.
