It’s hard to find hard information on this because hard statistics are difficult to measure - but I certainly don’t believe the evidence shows the number of bitcoin uses in the world is dropping, and anecdotally you just have to look at the millions of passionate and dedicated bitcoin and crypto users on this forum and Twitter and Facebook and Telegram and on the reddit bitcoin and crypto forums to think this isn’t just a fad that’s going to go away.
But looking for hard evidence your comment did inspire me to make a post looking at the best estimate possible for bitcoin ownership and use in the world -
https://bitcointalk.org/index.php?topic=3238611.new#new - and the figure I came up with was indeed 0.5% of the adult world population using and owning bitcoin.
Is that figure growing? Well Statista’s figures for wallet addresses in the world holding BTC were 5.5 Mil at end 2016 and 11 Mil at end 2016 and 21.5 Mil now -

And will that figure of 0.5% of adults worldwide owning BTC grow. These are figures from a Statista survey last year showing that 40% of Americans were open to the idea of using bitcoin for transaction purposes, and that 40% of Americans aged 24 to 39 plan to invest in bitcoin as an asset for the future -

But the mempool is now empty and transactions are fast and cheap again, and there are 200+ top developers working on six projects to get bitcoin ready to cope with the next stage of its growth - and as we’ve seen there’s a population primed and ready to own and use bitcoin and crypto, and I have no doubt that 0.5% active user figure will increase to 10% active users over the next 5 to 10 years with bitcoin close to or worth over 100 K in five years time.
And in relation to businesses accepting bitcoin here’s another Statista survey last year, that showed 3% of Americans businesses plan to accept crypto including BTC as payment within 12 months and that 12% plan to do so within 1-3 years
