Finding coins with a setup similar to SUI—combining institutional milestones with oversold technicals amid a choppy market—highlights a few key Layer 1 competitors today, March 13, 2026.

1. Aptos (APT) – The "Institutional Twin"

Aptos is currently mirroring SUI’s narrative almost exactly. It is benefiting from strong institutional "Move" language sentiment but is struggling with short-term price gravity.

Price: Trading around $0.91 - $0.96, down nearly 8% over the last week.

Technical Setup: Similar to SUI, its RSI is dipping into the 30s (nearly oversold), and it is trading below its 50-day Moving Average ($1.22), confirming a bearish short-term trend.

Similarity: Like SUI, Aptos is frequently cited in institutional research as a leader in scalability and sub-second finality.

2. Celestia (TIA) – The "Oversold Modular Play"

If you are looking for a coin that is even more technically "stretched" (oversold) than SUI, Celestia is the one to watch today.

Price: Hovering near $0.32 - $0.34.

Technical Setup: The sentiment is 82% Bearish with a 7-day decline. However, its daily RSI has reached levels not seen in months, with some indicators showing a Stochastic RSI of 100 (overbought on a micro-scale but deeply oversold on the macro).

Similarity: It shares SUI’s "Extreme Fear" sentiment (Index score of 18) but has strong fundamental backing due to its modular data availability dominance and the upcoming V7 launch narrative.

3. Sei (SEI) – The "High-Speed Underdog"

Sei is often grouped with SUI and Aptos as the "new-gen" high-speed L1s. Its data today shows it is fighting the same bearish pressure.

Price: Approximately $0.062 - $0.065.

Technical Setup: SEI is currently trading below its 200-day EMA ($0.065), which is acting as a heavy ceiling. Its RSI is also in the neutral-to-oversold territory.

Similarity: Much like SUI’s recent ETF news, SEI has its own "real-world" institutional catalyst with the Xiaomi partnership implementation. #SUI🔥 #Aptos #TIA🔥🔥🔥 #SEİ
