Yes, absolutely. They initially asked for $10K. They now have 10 times as much.

To pause the contribution round now and to show they can deliver would help them in avoiding the enormous risk of as someone else here already mentioned of becoming 'the next cuil'.

Hype is a double-edged sword, it's great when you have it but you only get one shot at delivering and in an overhyped situation that is much harder than in one where expectations are still realistic. The more money they pull in the more this will be overhyped, the bigger the chance of a public disappointment when they launch.
