preference between stock and great Bitcoin?
This can't be without the level of knowledge, history and peoples experience, personal and immediate interests and trends.

People's orientation to life can affect their preferences. Looking at stock and thinking of how long it has been some will without any look on Bitcoin always invest on stocks and this most have been the case for many people.

Looking at trends which is still a result of orientation to life, Bitcoin is top preference.

Immediate interest could be how quickly returns you need which likewise influences certain response

The people around someone can be a great influence too. E.g being around someone from this forum could likely make Bitcoin the most preferred.

For me, venturing into both is the case so that the preference wouldn't be permanent but based on concept at one point or another.
