I guess I'm more thinking of the non-extreme cases like above (highly unlikely use case for developed nations). Namely, what do you think of it, not as ETF or investment, rather as a medium for exchange in everyday life, in side-by-side existence with the USD or EUR for instance.
BTC as an investment feels empty to me, unless it has a strong functional case as an actual currency.
If Bitcoin is nothing as an investment, it is like it has no value.
If it has no value, it can not be used as a medium of exchange daily because nobody will want to make a trade deal and in return, will receive something that has no value. If you want it to be used more, it must has value as a mandatory condition.
It can be used globally, cross borders, cross nations now but as a currency for daily fund transfer, for everyone, it is not for now because of mempool congestion and very costly transaction fee for small value transaction.
If you want to move a big fund, Bitcoin blockchain is for you, because transaction fee will not be your issue and transactions on Bitcoin blockchain is much safer than bank transfer.
By big fund, I meant $10,000+
How many Bitcoin confirmations is enough?1 confirmation: sufficient for small payments less than $1,000.
3 confirmations: for payments $1,000 - $10,000. Most exchanges require 3 confirmations for deposits.
6 confirmations: good for large payments between $10,000 - $1,000,000. Six is standard for most transactions to be considered secure.
10 confirmations: suggested for large payments greater than $1,000,000.
