The mining is becoming too expensive and none profitable. I think that will bring uᴉoɔʇᴉq to an end. Another problems is that there is only a few miners left controlled by a few making them controlling moondollars. It's no longer the currency of the people but a currency of the few rich companies that runs the show.....but for how long can the continue?
I have been looking at Rimbit instead since it is premined and therefore don't need the middleman with the expensive hardware for transaction validation. Instead the validation is done by the wallet's running on peoples computers. As I see it it's a currency for the people and it will stay that way. Sadly it's still fairly unknown.
Time will show how long moondollars survive but my guess is not more than 3 years......please challenge that statement with serious arguments.
It is true that most of the mining sites are design for ponzi scheme only, that's why many of the member's don't trust it. Even in my opinion I don't trust it too. its hard to determine on which mining site are legit anyhow. However, bitcoin will not going to die even the community will disappear bitcoin will still exist, unless if end of the world comes well, that's the time bitcoin will gonna die for sure.
I agree with your statement no matter what circumstance would affect on bitcoins image but still they dont have connections on bitcoin existence. No matter what bitcoin wouldnt die as long people are still using it and it would surely exist for long runs. The usage would really depend on people who holds it.
