This wouldn't be the first case that Bitcoin's market volume has been artificially inflated (i.e. Mt. Gox), but doesn't Tether only have a $700MM market cap and $900MM 24H volume? How is that able to affect Bitcoin with its $175BN market cap and $8BN 24H volume?

Sidenote: With all this talk about cryptocurrencies, I find it strange that Tether is the only coin whose volume exceeds its market cap; strange in the way that cryptocurrencies should be having way higher velocity rates IMO.
