It's quite strange question, but there's a flaw to it; you can't not know that you not know, because the second you do, you no longer not know.
I'll be interested to see some of the attempts tho, but i'm fairly certain i'm right.
You're right. It's a paradox. The act of identifying something as an unknown-unknown changes its character to "known unknown."
I make this thread half-jokingly.
there is an infinite number of unknown unknowns with also unknown probability scale, so speculation on such matters will not be beneficial.
I can make one categorical prediction, though:
it will be impossible for bitcoin to be both a dominant cryptocurrency driving world's commerce and having just 21 mil units of account.
I know about infinite divisibility, but such matters will look progressively silly at some point and there will be pressure to allow for more coins.
Maybe bitcoin will be a founding substrate of another coin (
BTC 2.0), but the total coin number will not be fixed at 21 mil in perpetuity.
There will be unbearable pressure on developers to adjust in some way...and they will.
