Bitcoin (BTC) price fell to its lowest levels in a month on Feb. 28 after another day’s losses underscored continued selling pressure on markets.

BTC price clings to $8.6K

Data from Coin360 and Cointelegraph Markets showed BTC/USD hit five-week lows of $8,455 on Friday.

At press time, volatility abounded on exchanges, with Bitcoin shedding roughly 3.3% overnight to fluctuate around $8,600. Weekly losses totaled almost 12%.

Analysts had pinned their hopes on the largest cryptocurrency defending its 200-day moving average at around $8,800. This failed to hold, however, opening up the potential for what Cointelegraph Markets analyst filbfilb described as a “significant issue.”

Bitcoin’s weakness closely tracked a day of horror for traditional investments, with the Dow Jones seeing the biggest one-day drop in history on Thursday.

Tormenting sentiment was coronavirus, the spread of which has now become more intense outside its country of origin than inside. While the United States government played down the risks, Cointelegraph reported that traders now overwhelmingly bet that the Federal Reserve will significantly lower interest rates this year to boost economic growth.

At close to $8,600, however, Bitcoin is still performing in line with technical expectations. The popular and traditionally accurate stock-to-flow (S2F) price forecasting model calls for an average $8,606 for BTC/USD in the run-up to May’s block reward halving.

“A few weeks before every halving, #Bitcoin touched the #s2f model price. This time it is no different,” Twitter-based analyst CryptoKea summarized.

Despite facing criticism of his model, stock-to-flow creator PlanB has so far stuck rigidly to his long term target for Bitcoin. This calls for an average of $100,000 between 2021 and 2024.

Altcoins see another day of sell-offs

Across altcoin markets, most major coins saw losses of between 2% and 5% on Friday. Only Chainlink (LINK) and Huobi Token (HT) made gains.

Ether (ETH), the largest altcoin by market cap, fell in line with Bitcoin — 3.1% to hit $221.

The overall cryptocurrency market cap was $244.5 billion. Fellow Cointelegraph Markets analyst Michaël van de Poppe warned that should that level not reverse upwards, his next short-term target lay below $200 billion.

“If we hold this level, we make a strong S/R flip. If not, I'd be aiming at $195 billion next,” he wrote in a Twitter update.

Bitcoin’s share of the market remained almost unchanged at 64.1%.
