It's not about
believing, it's about
doing. If the Qora community as a whole can fix the flaws in its code, then it can succeed. If not, then not.
A point in favour of Qora is that it should be an attractive option for "dead coin collectors" because it at least has some unique selling points. If a dead coin collector with some programming skills is found, then the future should be bright (at least, compared to now

).
This looks like an interesting idea:
Would'nt it be possible with smart contracts for example to set one or several bounties that would be only paid if someone gets the job done ?
And as far as I can evaluate the AT mechanism (without being a coder myself) that should be possible to do. The problem would only be to prove "that the bug is fixed". So there must be a possibility to vote for the "bounty donators", and that would require some trust in them because they could collude to "never pay the bounty to nobody".
