Isn't anyone worried about half the volume being on one exchange?
Arent you worried about BTC mining being centralised by 4 chinese people?
Yes, but seperate topic.
For me I remember the whole explosion of Bitcoin price at MtGox was driven by an internal exploit where they could buy bitcoin without spending any cash. For me I feel like half the volume is at poloniex, and a quarter is at Kraken. But other exchanges see like no volume. Just makes me leery thats all.
