I have searching the web all day all night looking for that scintillating cryto exchange platform that pays highest interest rate on coins you saved up with them per annum. The ones I searched on the web doesn't impress me like that, e.g cointiply, freebitco.in. they only pay 5 and 4 percent interest rate per annum for saving your coins with them. I'm expecting higher interest rate like 12%, 15% per annum, I believe I can find the result here. Is there any one here with a solution to my problem??
