I frequently use shapeshift to convert from bitcoin to many other currencies. Today I found the site ExchangeCompare.io that comapres shapeshift exchange rates to it's competitors.

For larger amounts (~1 BTC) I saw that a site called flyp.me is the cheapest. Honestly I never heard of them and I'm a bit afraid trusting them with my money. Does anybody have ever used them? Can I trust this site?
