The reported price at fiat/Bitcoin interface Coinbase almost exactly one hundred United States dollars per Bitcoin after a single sell of 265 Bitcoins demolished their orderbook. The Coinbase "exchange" like the Winkelvii (WOT:nonpeople, possibly arbuscular mycorrhizal organisms) operated Gemini exchange manifests a hypothesis made famous by the late American philosopher Yogi Berra that a venue can be so popular no one patronizes it. Coinbase exchange and anything the Winkelvii touch generate substantial lamestream attention creating an appearance of popularity, but incidents where people actually try to use these platforms to trade seriously reveal that there actually isn't anyone using the places to conduct their business.
