Of course the rapid fall has made me think about Bitcoin's chances. But without going into details, I don't think much anything has changed except the price.
Seems that there are enough people in the market now that think the complete opposite of what I do currently, concerning the relation of price and fundamentals

Not sure I understand what you mean here . . .
Are you saying that you don't believe bitcoin's fundamentals are strong and anyone buying has "the complete opposite" opinion of you?
No he's saying the opposite.
