Sia is pumping up,
BUT check this out,
on their website they claim that 1 TB for month will cost 2$ (https://sia.tech/)
But actually after latest pump it jumped from 5$ to 12$!!! (https://siastats.info/storage_pricing.html)
It makes the storage there, with their (sorry for my words) shitty (sad trues) app more expensive than google drive / drop box etc.
So be careful buying this one, it is now wayyy beyond the red line of the market cap which is 1.8$ billion (if it is lower, it is cheaper than dropbox/google)
It sounds cool, but my experience using it (https://steemit.com/bitcoin/@davidconstantine/my-experience-using-sia) and the price, are just not connected to reality.
