Exactly. I assume they’re targeting the “big guns” that can spend/invest money in order to build a Sia data center and then get a return out of it. I had a raspberry running Sia for a couple of months and made nothing out of it :-(
When I originally heard/read about Sia I had the optimistic view that many of us users would power their network, where in fact only a few ones exist (~350).
