Since nobody mentions it around here, Kraken is weirdly leading the decline. Currently 2-3% below BTC-e (!) already, 3-3.5% below Coinbase and Stamp. I've never see this before. There has to be a reason that people use Kraken to dump BTC. Perhaps because it's an easy gateway to ETC, which happened to go up 43% in the past 24 hr (in USD)?
thats a reasonable explanationpoeple cashing out of an already very profitable trade ( selling there duplicated coins for BTC ( free money WOOT!) ) probably have less of a problem DUMPING....
