I did say 90%, not all. I guesstimate 5% are lost and folks would hang onto a few percent. This is purely hypothetical and is highly unlikely to happen. So you do have a price, you just won't say.
Well, I have one for 90% of my
Bitcoins. But, for one it changes all the time, and more importantly, I can't tell what other people would charge for their Bitcoins, or how many are lost exactly, etc. I can answer a lot about what I would do, but "all of Bitcoin" appears fairly illiquid to me, so who knows what would happen? The offer itself would value Bitcoin high enough for those who keep them, no? Hard to think in this kind of scenario.
It's not just that I'm not telling, I can't decipher the question in a way that gives a clear result. Either it's my current speculation price, which I won't tell of course and is probably below the lowest entry in the list, or it's some price that is affected by the fact that some large company decided something concerning Bitcoin -- which is too fuzzy in this formulation. that said, I wouldn't know how to answer if I wanted to.
