Value versus Price is a very important thing to understand, if you are investing. Usually the price runs in front of the value, therefore people talk about a bubble. The bubble only bursts, if the value cant catch up to the price.
Bitcoin is a long way from adoption. The interface isnt really mainstream. Most people who came in December for the bullrun, didnt bother to take their bitcoins off exchanges. So I think we need the solve 2 main problems:

1. We need to have easy and memorable adresses
2. We need to have easy and secure private keys

If we have those, mass adoption can happen. I am betting on it and with Lighning Network there is some amazing technology ready to start... looking forward what else is going to come.
