Bitcoin has lost about of 7% of its value in the past 24 hours, currently trading at $6,780. The majority of the decline took place over a period of just recent hours, earlier today.
I guess that we have seen the sharp price decline because CFTC has requested trading data from crypto exchanges: Coinbase, Bitstamp, itBit and Kraken.
It's no surprise that these platforms might be involved in crypto price manipulation - we will see about that soon enough.
