How can Gemini avoid the manipulation of the price? How can any exchange do this anyway?
I was referring more to the manipulation by the exchanges themselves rather than the maniacs who use them. It's unproven in most cases but I'm sure it's been par for the course for a long time.
However what many Bitcoin traders regard as legit tactics is actually against the law in no shortage of jurisdictions for conventional markets.
Quoting this by the Winklevoss
Cameron Winklevoss added that Gemini has "the highest regulatory policies and capitalization requirements." The brothers said they implemented background checks and protections against money laundering.
And, moreover, they said they want their exchange to be legal so they backed fund into federal accounts.
They said they want to act respecting the law.
This does not assure they will not use any fractional-reserved based system.
