Did someone actually say this? This is 2011 talk. There IS a steady growth of services and stores. It's not a matter of "appear," it's verifiable using hard statistics (number of businesses and services currently accepting, number of charities accepting, less linear measures such as tx volume, blockchain tx, etc etc etc).

There IS a steady growth of services and stores accepting bitcoins. Your perception and the way it "appears" to you doesn't matter - go look on the internet, it is impossible to make the case that adoption is flatlining or decreasing using verifiable data. Feel free to make up some data to support your claim, though. Here, I'll do it for you:
"Lol, guys, last month, 1,000 businesses on earth accepted bitcoin. This month, only 754 businesses accept bitcoin."
There, I said it. Doesn't make it true.
