What looks like insider trading from Coinbase with lots of people buying up BitcoinCash just before they announced it would be immediately available on their platform, and coincidentally the CEO of link to Bitcoin! (main figure in Bitcoin Cash) happened to sell his Bitcoin for BCH.
And the creator of Litecoin selling all of his LTC.
He indicated that this was to separate his comments about LTC from any direct financial incentive to avoid any assumptions or speculation about his motives
All very interesting and a sign that 2018 will have a lot of opportunities.
