i think there may be outside influences that can help to multiplier the number of users, and this can be if the CBDC comes all the people can be familiar to the "blockchain money" and having a wallet etc, also all the old people who died its surely not an user of BTC, but most of the young yes, so we are up.

So if you already have some cryptocurrencies, in someway you always ended having some BTC i think.

But i don really like to put numbers or approximations because you know its really tricky to do.
