Cryptocurrency prices continued to tumble Friday with Bitcoin leading the charge, with prices for the internet currency dipping below $50,000 for the first time since early March.

Bitcoin is down roughly 20% week-over-week, around 30% from its all-time high of nearly $65,000 early last week. The market cap of the coin has dipped below $1 trillion. The tumble has been less severe for Ethereum, which hit an all-time high just yesterday but has since dropped 13% as the broader market has crawled back.

Plenty of altcoins have also taken a beating. Dogecoin erased the breakneck gains of the week and then some, nearly halving its price after a meteoric climb last weekend. XRP is down 35% week-over-week, Stellar is down 30% and Polkadot is down 25% since last week.

Overall, Coinmarketcap estimates the global crypto market has shrunk around 10% in the past 24 hours.

Crypto prices have been on a tear for the past several months, but the past week has been the clearest sign of a correction to climbing prices, though many see news of President Biden’s adjustment to the hikes on the capital gains tax as the most apparent reason for the market’s slide as investors cash out hoping their gains won’t be reached by a retroactive application of the rules.

Coinbase, which went public last week via direct listing, shaved about 10% off its share price this week, but was largely unaffected Friday in intraday trading.
