as others said before : to much supply to get to this price (1$).
I dont see any chance that sia is going to have 10% share of the world wide cloud market.

Also my opinion is that hardware prices and storage prices for 1 TB sia are too low.
ROI is terrible, uptime must be 99,99% percent what is not possible to run that on a home pc system.
internet providers don´t provide 99,9% uptime, why should they ? thats only possible in data centers where the infrastructure is way better than copper or fiber to home wires.

Sia hosting is profitable when you have acess to:

cheap hardware without VAT
cheap electrical costs or solar energy at home
good internet connection which states that you have a expensive contract with a internet provider.

so hosting is only possible as running as a business, otherwise its really gambling. And for that there are better cryptoassets to speculate out there with better ROI and sharp ratio.
