A pseudonymous analyst has highlighted a descending resistance trendline and horizontal support on the XRP/WTI crude oil chart, with major resistance around 0.0440 and key support in the 0.0270–0.0290 area. XRP, which has been in a sharp three-month decline against oil, is now trading near 0.0335, just above an intermediate support level, and the analyst suggests a breakout above the diagonal line could trigger a strong rebound.

XRP has dropped into Santiment's "fear zone," where strongly negative social sentiment has often appeared near local price bottoms. While trading around the $1.83–$1.87 support band, XRP is showing stabilizing price action and small higher lows on the 12-hour chart. On-chain and technical indicators such as CMF suggest selling pressure is easing and that capital may be starting to flow back into the market, increasing the odds of a near-term bounce.
