Right now BTC is around $71.8K, up about 1.6% on the day, after pushing near $72K intraday. This comes right after Friday’s run toward the $73K–$74K area, so part of what you’re seeing is follow-through from a strong late-week move rather than a totally random Sunday explosion. 

The bigger drivers look like this: spot Bitcoin ETF inflows picked up again last week, and Strategy/MSTR bought about $1.28 billion of BTC between March 2 and March 8. On top of that, market sentiment improved as fears around oil/inflation eased and headlines suggested Middle East tensions might not spiral as badly as feared. That combo has been pushing crypto higher for several days already. 

Why does it feel extra wild on a Sunday? Because Bitcoin trades 24/7, while U.S. stocks, ETFs, and a lot of traditional market plumbing are effectively offline for the weekend. That means thinner liquidity and fewer active desks, so price can jump faster on relatively less flow. Kaiko notes weekend BTC spot volumes are usually much lighter than weekday activity, even though they spiked recently after the geopolitical shock. 

So the clean read is: yes, Sunday spikes happen — and this one looks like a mix of real bullish catalysts plus weekend market structure amplifying the move. The real test is whether it holds when Monday liquidity comes back.
