Goldman Sachs customers received a letter in which analysts of the bank warned that the price of Bitcoin could soon fall below 6000 dollars. The team of technical analysts of the bank is headed by Sheba Jafari, who is sure that the market decline began with the large sales of Bitcoins, which previously belonged to the MtGox crypto exchange. As it became known, the head of the board of trustees of the exchange Nobuaki Kobayashi organized several rounds Bitcoin sales to pay off creditors MtGox.
