The bitcoin(s) I've received in signature campaigns are minimal compared to what I've bought myself so I'd absolutely care about bitcoin if signature campaigns were stopped. I check the price multiple times a day, I've educated myself on security to ensure my bitcoins are secure in offline cold storage. I actually enjoy being in a signature campaign, it's quite fun, gives me something to do when I'm bored. Sure I'd post less if I wasn't in a signature campaign but that's natural I guess.
Pretty much most of ^this^. Bitcoin isn't really first and foremost about the money for me, it's the whole concept of it and its reasoning for creation/existence that interests me, and the fact it draws attention to the broken financial system like nothing except a crash does/has. I see it as a tool for ones freedom and sovereignty.
I see it as one of the most important inventions - at least in this century - and comparably in history too. Note I say 'one', not 'the', because no one can deny 'the wheel' or anesthetic.
A sig campaign is just a nice addition for posting what I would already post anyway. I think it also depends on how you take the minimum or maximum required/allowed posts though too. Either way, it might lead to many posts or too little. The one I'm with seems about right for my usual amounts of posts when I'm a member of a forum.
And besides... it'll pay for the Trezor I've already bought... which of course, has now gone down in price to $99. If only I'd waited a week or so
