Bitcoin sheds 2% to near 15-month nadir

Bitcoin fell over 2% on Monday after a hiatus from gains for two days, nearing 15-month lows anew amid mounting regulatory concerns in the US. 

At Bitstamp, Bitcoin shed $79, or 2.2% to $3,450, with an intraday high at $3,588, and a low at $3,442. 

Bitcoin rose 3.8% on Sunday, the second profit in a row away from 15-month lows at $3,210.

Market value of cryptocurrencies fell $2 billion on Monday to a total of $112 billion, after hitting $104 billion on Friday, the lowest since August 2017. 

Last week, Bitcoin lost 13.9%, the fourth weekly loss in the last five amid a crypto selloff wave. 

The US Securities and Exchange Committee (SEC) decided to put off its decision on enlisting Bitcoin exchange-traded funds yet again. 

Another final deadline was put off to February 2019 to conduct further reviews. 

The SEC said it needed a longer duration before taking the decision to approve or reject the proposal in order to look into the the merits of the decision.
