Adoption is dying out ...
How did you arrive at this conclusion? The exchanges, which people use to exchange fiat to Bitcoin
are drowning in support requests and user registrations. Some exchanges had 100k unique customers
signing up for an account in a single 24hr period. Bitcoin is all over the mainstream media and
much more known that it was a few years ago.
Merchant adoption may be a bad metric to measure the success of Bitcoin.
You are looking from a wrong angle if you reduce Bitcoin to its value as a payment
system like Paypal. How about the other features like an immutable ledger, a censorship-resistant
store of value...?
