What happenend with the price? 
Speculation happened. It will recover as it always does.
Well, I hope so. I bought it at a much higher price a couple off months ago.
You will be laughing your way to the bank in a couple of years. Sia actually has real cloud platforms using it as a backend.
I've got some extra siafunds to sell. Selling 10 SiaFunds @ 3BTC each, which is the going rate over on the Bisq exchange.
