I think a lot of people are using Bitcoin as a store of their wealth and not as a digital currency and that's why we are seeing such abnormal jumps in the price.
Yes - the consensus now is that bitcoin is an asset not a currency, and as a result it is behaving very similarly to gold.
even bitcoin became salary for they living, bitcoin became their main jobs to have a living. but exactly as you said a lot of people using bitcoin became an asset,rarely to find people who using it become a currency.
i think we still have a really long time to go until we will reach such a bitcoin popularity that would allow people to work for bitcoins only and to gain their wage only in bitcoins
thats true that after such a huge grow it is impossible that the price will be stable because people are dumping their bitcoins at a very rapid pace then in order to make big profit
