Bitcoin and Ethereum are holding in narrow ranges while XRP has retreated as optimism over a potential US-Iran nuclear deal fades and risk appetite softens across digital assets. Bitcoin is hovering near recent support levels and Ethereum remains rangebound below key resistance, signaling a market where neither bulls nor bears are firmly in control. Reports that negotiations between the US and Iran have stalled have dented a broader risk-on mood, and analysts note XRP is showing the sharper move because altcoins can be more sensitive to speculative flows. The next phase for crypto prices may depend on geopolitical headlines, official statements and macroeconomic data, while technical levels in Bitcoin and Ethereum remain important gauges of trend strength.
