Freebitco.in you get like 4% interest annually but I wouldnt trust my money everywhere
Ha ha....
4% interest on bitcoin, which is an appreciating asset? How do they generate these returns?And what happens if they fail to generate these returns. The better option is cold storage and taking advantage of airdrops like byteball.
This is not that much really
At any decent exchange you will get a lot more on average, though your interest is not guaranteed there, of course. But, strictly speaking, it is not guaranteed at freebitco.in either. Regarding generating returns, freebitco.in is a dice site, and they have a house edge which is way higher than at most "regular" Bitcoin dice casinos out there. The house edge across the "market" seems to be around 1%, while it is like 5% at freebitco.in (if I'm not mistaken). Further, they are aggressively advertising via Google AdSense, so their revenue flow from ads may be well above interest payouts (read it can be quite profitable overall)
