Bitcoin Drops to $76K; Altcoins, S&P and Dollar Tested

Bitcoin pulled back to roughly $76,000 on Monday as several large altcoins slipped below short-term support levels. Traders pointed to heightened geopolitical tensions and changing institutional flows as factors tied to the retreat.

Comments from former President Donald Trump warning Iran that the “clock is ticking” were posted before markets opened. An analyst on X wrote that a potential U.S. military operation against Iran would be “extremely dangerous for $BTC.” Data showed spot Bitcoin exchange-traded funds recorded about $1 billion in weekly net outflows, the first weekly outflow after six straight weeks of inflows totaling roughly $3.4 billion.

An SEC filing reported that Strategy, the largest public holder of Bitcoin, purchased 24,869 BTC for about $2.01 billion between May 11 and May 17, increasing its reported holdings to 843,738 BTC.

On technical charts, Bitcoin was trading near its 50-day simple moving average, around $75,600, a short-term support traders are watching. The 20-day exponential moving average sits near $78,700; a sustained close above that level would be an early sign of renewed upside momentum. A close below the 50-day SMA could expose the price to the support line of the ascending channel and targets near $65,000.

Ether fell after closing below the support line of its ascending channel. The 20-day EMA for Ether is near $2,255 and momentum indicators were near oversold readings; failure to reclaim the 20-day EMA would increase the chance of a move toward $1,916. XRP traded under its 50-day SMA at about $1.39 and may test $1.27 next, with lower levels at $1.11 and $1.00 if selling continues.

BNB pulled back after failing at $687 and dropped beneath its 20-day EMA near $648. The 50-day SMA around $637 is the next support, and a breach could send the token toward $570 and then $500. Solana closed below its 50-day SMA near $85, with immediate support at $82 and a lower target of $76 if selling pressure persists. Dogecoin slipped under its 20-day EMA near $0.11 and was range-bound between about $0.09 and $0.12.

Smaller tokens showed mixed action. Hyperliquid traded above $45.77 at one point but produced long wicks that indicate selling near higher prices; its 20-day EMA sits near $42.55 as the short-term downside barrier. Cardano moved below its 50-day SMA around $0.25 and oscillated between $0.22 and $0.31.

Equity and currency moves provided additional context. The S&P 500 rallied to an all-time high of 7,517 last Thursday before profit-taking, leaving the index positioned to test the 20-day EMA around 7,273. A rebound off that moving average with momentum would point toward a potential resumption higher; a drop below the 20-day EMA could open the way to a deeper pullback near 7,002. The U.S. Dollar Index turned up from a 97.74 support level and moved above its moving averages, facing minor resistance at 99.34 and stronger resistance at 100.54; a sustained close above 100.54 would put 101.97 into view, while a reversal under the 50-day SMA near 98.98 would suggest continued range trading.

Market participants said they will watch whether buyers can defend near-term crypto support levels and whether flows into or out of Bitcoin ETFs stabilize in the coming days. Geopolitical headlines and weekly institutional flows remained items traders flagged as potential drivers of short-term price direction.
