I would even say that there are 5 types of attitudes towards BTC:
1. Denial.
2. Scepticism.
3. Interest.
4. Confidence.
5. Bitcoin evangelism.
You may not be wrong with this logic, but I think points 3-5 are just the same thing, because first you need to pick interest, and after you have really gotten a good understanding or experience, you will be more confident, after which you will want to let others know and enjoy the benefits of Bitcoin, which first is true decentralization. Also, those who are skeptical about Bitcoin will not buy the idea of having to deal with it (denial). But you did not mention those who have misconceptions about Bitcoin; their misconceptions may be due to some economic lies or some bad experience they or their friends have had with some shitcoins in the past. The truth is that everyone doesn't really need to have a good view of Bitcoin for it to exist. Bitcoin will remain unchanged from what it is, and before some people realize they were wrong about Bitcoin, it might have been too late.
