Bitcoin dips below $80,000 as May 15 spot ETF outflows near $290M weigh on crypto

Bitcoin slipped back under the $80,000 support between 12 and 16 May after repeated failures near $81,000–$82,000 and broader profit-taking. The pullback coincided with heavy ETF selling pressure, including roughly $290 million of net outflows from U.S. spot Bitcoin ETFs on 15 May, while spot Ethereum ETFs saw $65.66 million in outflows. Several major altcoins also fell, led by Solana down nearly 7.9% and Cardano down over 7%.
