There is no adoption at all. New wallets are only being created by existing users - adoption is actually negative in terms of real users
Do you have any source or any statistic which backs your claim ?
I don't know what you are thinking about when reading the word
adoption. But this is a slow process.
More and more merchants are starting to accept bitcoin. The number of BTC user in countries with a broken financial system is rising too.
If you look at the
number of open channels on the lightning network you will see that there is a big community which already starts to use the LN on the mainnet even though it is still in beta.
Once the LN is ready and running, there won't be any factors holding mass adoption back anymore.
