The asset has dropped from 0.0403 to 0.03561 — an 11% decline. The RSI reading at 15 suggests the asset is oversold. Volume is moderate but beginning to taper off, suggesting that sellers are losing conviction. The 4-hour chart shows a steady decline, but the momentum is slowing significantly. This level has historically attracted buyers, and support tends to hold until there's a significant shift in market structure. If buyers defend this zone, the next resistance areas to monitor are 0.0360 and 0.0366, with deeper liquidity resting at 0.0378 — a 6% upside from entry. The stop is placed tight at 0.0354, below the recent low.
