Cryptocurrency markets experienced a sharp sell-off on August 21, led by a 700 USD drop in Bitcoin during early morning trading. The overall market valuation of over 2,000 digital assets has fallen to 263 billion USD, with most coins losing between 2% and 8% of their value. Bitcoin currently trades at 10,124 USD, down 5.8% in the last 24 hours, and holds a 69% market dominance with a valuation of approximately 181 billion USD.
Altcoins Follow Bitcoin's Lead
Ethereum (ETH) fell to 185 USD, a daily loss of 5.8%, with 7.4 billion USD in global trading volume. Ripple (XRP) showed relative resilience, dropping only 3.3% to 0.26 USD, though it has lost 4.9% over the week. Litecoin (LTC) slipped 3.5% to 72 USD, while Bitcoin Cash (BCH) declined 5% to 299 USD, with a market cap of 5.3 billion USD and daily transactions of about 43,000.
Market Sentiment Turns Extreme Fear
The Crypto Fear & Greed Index, which aggregates sentiment from multiple sources, plunged to 11, marking "extreme fear" territory. Just a day earlier, the index stood at 39 (fear). Despite the panic, some traders remain constructive. Popular analyst Jacob Canfield described the current chart pattern as a "classic rising wedge hitting resistance" and suggested an ideal buy zone of 8,900-9,100 USD if support breaks. However, Mobius Capital Partners founder Mark Mobius dismissed cryptocurrencies as "psycho currencies" based on faith rather than fundamentals.
Central Banks Fueling Crypto Demand?
In a column for the Nikkei Asian Review, Financial Times chief correspondent Henny Sender argued that central banks are inadvertently driving demand for Bitcoin. "Central banks have played a big role in driving this latest rally in crypto," she wrote, noting that competitive currency devaluations in response to trade wars are pushing investors toward digital assets as safe havens. This view is supported by the fact that traditional markets such as stocks and bonds have also been shaky, prompting both institutional and retail investors to hedge macro risks with cryptocurrencies.
As Bitcoin and altcoins fluctuate, short-term traders face pressure from weak hands and short-sellers. While long-term believers remain cheerful, the extreme fear reading suggests that the market may need to test lower levels before finding a solid bottom. All eyes are on the 8,900-9,100 USD support zone for Bitcoin's next move.
