Bitcoin is the worst possible 'store of value'in any financial scenario.
It's highly volatile, subject to unknown future regulations, competition from other things - and of course, it could go to zero tomorrow.
Moreover - there are any number of other, better opportunities for 'store of value' - most notably real-estate.
There has been demand for real-estate in London for at least 1000 years.
So think, in 100 years, will there be at least some demand for real-estate in London. Probably. Probably more than today - but at least some.
What will the demand be for BTC in 100 years? Will it even exist? Will anyone even remember what it is?
The volatility alone makes it really not something you want to 'store a lot of value for the future'.
Just because there is pragmatically a 'fixed number of BTC's that will ever be created, and that it has some crypto-viability - does not inherently make it a 'good store of value' - or a 'store of value at all'.
