Is price the most important driver of your interest in Bitcoin?
Technical guys like early adopters of Bitcoin many years ago probably did cared more about technology and they started their adventure to decentralization with Bitcoin. For most of other adopters, they are more keen on chances to get profit in different stances like as investors, traders, speculators. They all do care about price of Bitcoin together with some different interests depends on who they are and what they want to do with Bitcoin and their money. Investors will have different interests than traders and speculators.
I would say it is 50-50
The price action is half of the fun. The tech is the other half.
I am pretty sure that is the case for many bitcoin holders. Some people obviously are not interested in the tech and only care for the prices but I dont think they are the majority
Do they have fun with price with different interests in technology and price or their portfolio?
I believe price is important for both types of people because price reflects many things like adoption in the community and value of Bitcoin. Value should be low if technical developments to satisfy needs of community, users, tech guys are not good enough. So as technical enthusiasts, they can not simply look at Github development activities but also have to look at how latest developments are either adopted or refused by users.
In another side of view, investors, traders, or speculators have to know that it's hard for price to move up a lot or make a parabolic curve if behind the scene, no developers are working and actually released upgrades for Bitcoin.
