No, paying a high price is never a good thing, not in memorabilia either. If you can pick up a Picasso on a flea market for $100 it's still a Picasso and a steal and good for you. Too bad for the seller if they're unaware of the market value of their merchandise.
So what should be the market value of Bitcoin?
That's for more than one person to decide. That's why it's called "market value". I'm not a dreamer and I find speculating on other people's dreams too risky so for me the value is zero.
