I had started reading about that and Siacoin a while back. Never got around to starting a node or anything like that. With Sia at least, you had to put up a stake first before you could start a storage node (for reasons that made sense). But then I'd have had to go through the rigamarole with buying some other coin, trading for it, setting up various wallets, etc.

Maybe at the end of the day I should just be giving a little money to rsync.net or Backblaze.
