For now I think bitcoin is a bit stable. Banning and other negative issues had been overcomed by the trust some company gives by supporting the use of bitcoins and the legalizing of bitcoins in some countries lessen the fear of bitcoin holders. I think bitcoin prices will be going up again.
In my opinion Bitcoin prices have not been stable, therefore prices are rising rapidly and also falling rapidly. For me it is great if bitcoin prices are more stable. Maybe bitcoin can be currency.
