It is stable enough to be able to convert bitcoins to usd at predicted rate (marked is liquid enough - and this is where speculators are good evil).

I am converting to usd only part needed to pay suppliers and rest leave in coins for now. Agree, income is fluctuating. But I am ok with it since so far I did not see technical issues with bitcoins itself.

But you are right - as I said below, huge fluctuation (although, what time period you used for 1000% fluctuation claim?) is a problem. And I will welcome stabilization at any level. Although market is too small to be stabilized soon.
