In my opinion people are dealing in alternate currencies because nobody is developing off-chain solutions to move all the junk to.
There are plenty of places those could go, the problem is that no matter what solutions you offer, what are you going to do if they DON'T WANT to move there?
-Hey bear, look, nice woods, I put food there in the forest, no cars, no stupid people
-Nope, I like trash, I feel fine in your yard!
As long as sidechains are not that profitable for ordinals and posers like bitcoinmagazine which is putting every single month one huge 4mB cover in the chain you won't get rid of them!
So, when somebody is blocking the way and doesn't want to move, what would a normal guy do? Chose another way to get to work, and in this case people who want to make cheap trsanctions migrate to either LN or accepted altcoins like USDT or doge.
but yet the sole objective is not defeated as it still remains the top modern day digital currency that is trying to find it's way to become the most preferred monetary system all over the globe as it's adoption continues to grow despite the low percentage.
If we have adoptions as you claim but we have less p2p transactions and more inscriptions and transactions to CEXs, then, well, it means exactly what the title about this is.
Edit: just saw stompix's post above mine and I agree, in the real world, everyone else might see Bitcoin differently, but I still tend to think those like me who found Bitcoin as a solution to every day problems like cross-border payments and remittances still see Bitcoin serve the same purpose. Yes, a lot more people I know online ask for payment in doge, ltc etc. But these are people who see and use crypto as cheaper alternatives to debit card or bank deposits for, say, gambling. Crypto was never a solution for them but a better alternative.
I always said that Bitcoin is the perfect tool, it gives you the freedom to use it as you want.
The only problem arises when the way some users want it affects others.
Much like your freedom rights end where my rights begin!
