After extensive an best high beforehand this month, Bitcoin prices are coming back to earth.

The accepted price (as of this writing) of $998 a coin is down more than 20-percent from its antecedent high, and down 10-percent today alone. As with all Bitcoin peaks, the fall is about just as dramatic as the rise, and often just as quick.

Bitcoin is a airy currency, so ebbs and flows — and often affecting ones — are par the course. This fall, however, may have been due, at least in part, to a few news belief over the past couple weeks.

As optimistic as some are about Bitcoin, news of the SEC shutting the door on the Winklevoss twins’ proposed exchange-traded fund (ETF) was the first of a series of dominos. An ETF allows an index, or a group of indexes, to be traded like a stock. In short, it would have accustomed quicker transactions and greater accessibility, as well as the adeptness to roll these indexes into advance accounts like an IRA or 401(k).

The SEC said it was “disapproving this proposed rule change because it does not find the angle to be constant with Section 6(b)(5) of the Barter Act, which requires, among other things, that the rules of a civic balance barter be advised to anticipate counterfeit and artful acts and practices and to assure investors and the public interest.”

After the SEC news, Bitcoin prices crashed, but bound recovered.

Since, we’ve also seen bad news from China. Currently, nearly all Bitcoin affairs come from Chinese exchanges, government regulators appear it would begin to crack down on the cryptocurrency. This led to China’s three better exchanges arty transaction fees on all trades, before eventually blocking barter from abandoning the currency.

And it’s not over. The SEC plans to make at least one more ETF ruling this month, and addition that could follow in April. One, or either, could send the already airy cryptocurrency reeling.
