I've had a lot of those same objections since I first heard about Bitcoin.
Ironically, I've been looking to buy some Bitcoin in the last couple months to trade for Sia, because I was thinking about setting up a storage node that can earn enough to pay for my own cloud backup needs.
I mined sia and eth together because there was a dual mining program. The idea behind it is kinda nice, I'm not sure I actually need the service right now... but I'll hang on to the 1k SIA I mined in case that changes.
I'm not expecting a speculative leap in value as amounts of siacoin mined are huge compared to the likes of ether or btc...
Do you need Sia to start hosting? I think you can just go for it.
Oh interesting, thanks for that. It puts up a bit of a barrier to entry... ooh, and suddenly things look a little bit complicated, as you have to manage your collateral levels optimally to get a good score and be an attractive storage option.
