It will surprise us again.
Personally I'd like to think it would - but you never know when it comes to the future. Anything can literally happen - just somethings are more likely than others. That being said, I'm inclined to believe that there are 2 major scenarios:
1) Bitcoin loses support over time and dies just like another fad. OP's prediction would make sense in light of a falling demand.
2) Bitcoin achieves more mainstream adoption and attention (alongside merchant acceptance) which would see a rise in demand and subsequently price.
I guess deep down we all know that 1) isn't going to happen. Let's take a look at it. Do you know anyone that abandoned Bitcoin after using it? Exclude people that got burned because they thought they are "traders", which they aren't. I don't know anyone.
Individuals have been slowly jumping on the 'train', companies and investors too. I'm saying we give this time.
I've always wondered why people are obsessed with the price? The price does not matter at all, unless you're here for the wrong reasons.
Can you use Bitcoin as a means of payment/transfer of value when 1BTC = $1? Yes.
