Fools and their fancy math theories.  You'll have your proofs once I take your bitcoin. 

It is 'mathematically impossible' (1/64,000,000) to win the lottery too, yet someone does it every week.

Id say the collision happened even when no one noticed it. Shit already broke you just didnt realize it yet. Whoever sends coins to the address in question first will reveal the information to the other person also in control.

Not according to quantum theory.

Storing data on a disk is not a quantum thing though. Even if, the data was stored at the very least in memory by a machine and thus it was observed. Furthermore it was not only observed but also modified and stored.

Agreed that current data drives and their storage ability are not directly using quantum
mechanics. My statements within this thread, originated after Danny commented to Franky's
statement: "schrodinger's cat - if you cant see it, did it really happen?", which Danny then advised
was not about whether it really happened, but that both have already occurred and both exist according
to quantum mechanics. I then commented about address collision in the context of superposition which
Danny expounded upon prior, and I stated that the blockchain may observe this collision itself. You then
commented to me stating "Id say the collision happened even when no one noticed it. Shit already broke
you just didnt realize it yet.". Then I replied stating that address collision happening without observation
is not possible in quantum theory, which was the only way I was discussing the topic from the start.
I was never saying or intending to say that Bitcoin address collision is actually occurring on a quantum
state, just the address collision prior to observation can be likened to the superposition in quantum
mechanics.

So it is interesting because the thread is about probability of address collision which can
be quantified, as you guys have done so already, but address collision like a superstate can not be,
and in that way, you can not tell me whether a collision has already occurred naturally, but only its
probability prior to observation. When the observation is made, and we can "know" yes or no, then
I no longer have interest since it has been solved and defined.

The reality here is that we are both correct as to our opinions and understanding, it is just that you
are talking about address collision in the probability provable sense and I am talking about it in the
quantum sense. We are both correct, but my comments should only be taken in the abstract, since
Bitcoin address collision clearly is not occurring on a true quantum level. Though it could be argued,
on the abstract, that all possible address collisions have already occurred prior to the creation of
quantum storage since that data would not be bound by spacetime, but that is another issue.

I did not intend to convey that unknown address collision was in fact a quantum superstate.

I support a decentralized & unregulatable ledger first, with safe scaling over time.

This should probably be watched by anyone who wants to use a brainwallet: DEF CON 23 - Ryan Castellucci - Cracking CryptoCurrency Brainwallets. He even posted an update (not entirely sure if the account is genuine):

The current release of brainflayer is much faster than what I released at DEFCON. Currently, it's only $40 to check 1 trillion passphrases on AWS, which works out to 25 billion per dollar.

Yes, that youtube comment is from me.

a trillion pass phrases. thats only:
9 alphabet characters deep
8 alphanumeric characters deep
7 alphanumericsymbol characters deep

When cracking passwords, exhaustive search with a character set is the last thing one tries. Breaking weak passwords and passphrases dozens or characters long or more is common with the proper tools.
