Really I think the only way Storj gets a good foothold is a MASSIVE disaster scenario like either Wasabi or B2 gets a complete data loss event or an entire AWS region is lost. Otherwise I see their customers being only:

1. Paranoid
2. Those who are subsidizing home backups by also running nodes
3. People who REALLY want the tech to take off

Once they go full production we may see a spike in usage but who knows.

The response from a dev I saw months ago seemed to imply they think that node owners will make money from bandwidth, as they can get $20/TB of bandwidth (no clue if this is before or after surge pricing ends) but I've yet to make more than $15 in a month WITH surge pricing sharing 4 TB with no bandwidth caps.
