https://www.trustnodes.com/2018/03/07/mt-gox-trustee-sold-half-billion-dollars-worth-bitcoin-bitcoin-cashThe MT Gox trustee has sold 35,841 BTC for $362 million and 34,008 BCH for $45 million according to reports coming out of a creditors meeting held earlier today.
Mark Karpeles, MT Gox’s former CEO, said the sums were “sold between December 2017 and February 2018 with the assistance of a bitcoin exchange.”
Little further detail is provided at this stage with a full report by the trustee providing no explanation why the funds were sold or why they were sold at this precise point.
A big sale like that could be the reason for bitcoin's downward pressure between Dec 2017 and Feb 2018.
