SiaCoin is a good strong buy due mainly to their intrinsic value (10x more cheap than AWS S3 and api for developper) and project that start to appear using Sia technologie like minebox.io. Moreover the fact of using smart contract to deal with the buyer and the lender help Sia to be more interesting that Storj. Also their software helps other people to use sia for personnal use which is not the case for S3. This help Sia to be a strong project and increase the demand in the long term. So with all this fundomentals and the fact that fibbonaci tells you don't sell until 0.00000785, SC/BTC is ready for a great bull market. Why I'm targeting 804 instead of 785? History has shown that in cryptocurrency people are more optimistic than 1.618 of fibo :)
