I think this is majorly affected by how you see or use Bitcoin as a currency or investment. Bitcoin was originally launched as a virtual currency for making payments all over the world. From this point of view I thing price stability will be more desirable as this will encourage the participation of business and merchants in Bitcoin world. This will impart more acceptability to Bitcoin. But from the view point of traders or investors a volatile market would be desirable.
Thats right. from that we will definitely see the answers people will choose to be stable and volatile depending on their interests in using bitcoin. but prices in the market will not be forever stable and not always volatile. I hope there is a new platform so that the use of bitcoin for currencies can be easier. where fluctuations will not be an obstacle for the seller or buyer
