It's really simple math. What is the failure or success chance for Bitcoin? Do you think it will fail with more than 90% chance?

Current value is the sum over each scenario's price times its probability. With the success scenario having people who estimate prices above 100 USD, those people will buy at 10 USD as long as they see a 10% chance of a full success happening! That's not strange, it's perfectly logic!

The question is only of quantitative nature, especially concerning the full success probability and the value it will have if that happens. Both are not known, so everybody takes a guess.
