Support Collapse in the Asia Session

$SUI has broken a critical 4-hour support level at $0.6729, sliding to $0.6696 as the Asia session progressed through early momentum. The 24-hour decline of -2.31% reflects steady liquidation pressure rather than panic selling, with $449M in daily volume providing moderate liquidity for the move lower. This breakdown occurred on above-average conviction, suggesting weak bids accumulated near the prior support zone.

The Structural Level Below: $0.6615

The next structural resistance turning support lies at $0.6615 - approximately 0.12% below current price. This level represents a confluence of prior 4-hour swing lows and aligns with a 38.2% Fibonacci retracement from a recent swing high. If $SUI closes the 4H candle below $0.6615, the path extends toward the $0.65 psychological floor and the 50% retracement level. Traders holding long positions from higher entries face a binary decision: defend the $0.6615 zone or accept further downside to test $0.65.

Price Action and Momentum Structure

The break of $0.6729 represents a loss of intermediate-term bullish structure on the 4-hour timeframe. RSI on the 4H has likely dipped into oversold territory (below 30), which historically invites mean-reversion buying, but oversold doesn't confirm a floor - it only signals potential exhaustion. MACD on the same timeframe remains negative, and the histogram has not yet flipped bullish, indicating the downtrend retains mechanical momentum. Volume during the breakdown was adequate, reducing the likelihood of an immediate bull-trap reversal.

What to Watch Next

Key price levels for the next 4-hour candles: a close above $0.673 would invalidate the breakdown and suggest a false break; a hold above $0.6615 could stabilize momentum before the next leg. If $0.6615 breaches on a 4H close, $0.65 becomes the tactical floor until proven otherwise. On-chain activity and whale accumulation near these support zones will determine whether current sellers are exiting on weakness or just repositioning short-term exposure. Monitor intraday bounces off $0.6615 for potential lower-timeframe reversal patterns, but do not extrapolate bounce strength as a trend reversal without a 4H retest and higher-high structure.
