Coinbase news was a pump&dump, exactly like the LTC on Huobi pump and all the other countless attempts to dump higher!
Insiders buy before anyone knows anything, all the other people buy at the announcement and at the countdown. Smart traders dump as soon as the site is online! [ ... ] Good thing coinbase is bringing regulation to BTC right? LOOOOOOOOL
@NYSE on Twitter, 20 Jan 2015:
"We will work with @coinbase to bring additional transparency to bitcoin pricing"
