GS: The bitcoin can collapse before it raises to $4,000

The period since the beginning of the year was good for the crypto-currencies. The bitcoin has risen from nearly $1,000 to $3,000 before ending the second quarter at $2,500. Or, it registered an increase of 168% in the first half of the year.
The strong rise in bitcoin levels has created serious controversy between Wall Street analysts and the technology world, whether the virtual currency is a "bubble".
Goldman Sachs, the state-owned investment bank, said the bitcoin could adjust seriously before rising to a new record high.
In a letter to clients of the financial institution, Sheba Jaffari, head of the US Banking Technical Analysis Unit, said the bitcoin had not exhausted its decline, which could take it to levels at least $1 857, which is a decrease of 25% of its current levels.
However, enthusiasts should not be bothered by the correction, but rather look at it as a good opportunity to buy bitcoins.
Because the correction, according to Jaffari, will be followed by a new strong appreciation of the crypto-currency, which would bring it to at least 3,212 dollars, with a potential for $ 3,915.
