Ethereum falls over 1% as most cryptocurrencies retreat

Ethereum fell over 1% on Tuesday on track for the first loss in three days on profit-taking away from week highs, while most cryptocurrencies lose ground on weak demand and lack of incentives to buy. 

At Bitstamp, Ethereum fell $2.50, or 1.1% to $225.15, with an intraday high at $228, and a low at $225. 

Ethereum rose 1.1% on Monday, the second profit in a row, marking week highs at $231. 

Ethereum lost 3.5% last week, the second weekly loss in a row on weak demand and as Ripple and other cryptocurrencies fell as well. 

Market value of cryptocurrencies fell $3 billion today to a total of $218 billion. 

Crypto trading volumes tumbled to July 2017 lows in October as current traders shun new positions amid a lack of incentives to buy. 

There aren't many important announcements that are expected soon, with the highly-anticipated US SEC decision on Bitcoin exchange trade funds expected in November.
