Mr. Luck "Lucky Bastard" L. Lucky von und zu Luckerton LVCXI is a punk who feels lucky today (like every other day in his life). He generates a BitCoin address, and activates the inbuilt mining program.

Mr. Lucky possesses this shockingly unexpected trait: whenever he uses a random or pseudo-random number generator (whether he runs it himself or someone else does it for him), he always gets the best possible outcome.

How fast will Mr. Lucky accumulate BitCoins?

As fast as it takes to compute 1 hash theoretically...

I'm somewhat amused by this thought. That it is theoretically possible that a Mr Lucky gets 15 million bitcoins overnight  Smiley

Anyone want to work out the probability of this happening? I imagine it's less than 1/((googolplex)^2)  Grin

It's unfortunate, he dies a death by lightning.

That evening, the lottery numbers are called.  The ticket on his refrigerator makes him a posthumous millionaire.

Companies claiming they got hacked and lost your coins sounds like fraud so perfect it could be called fashionable.  I never believe them.  If I ever experience the misfortune of a real intrusion, I declare I have been honest about the way I have managed the keys in Casascius Coins.  I maintain no ability to recover or reproduce the keys, not even under limitless duress or total intrusion.  Remember that trusting strangers with your coins without any recourse is, as a matter of principle, not a best practice.  Don't keep coins online. Use paper wallets instead.

If my calculations are correct, the odds are around (1/(1.0043516 × 10^59))^15000000 (which Wolfram tells me is 10^-(10^8.95))

In contrast, the odds of being struck by lightning are around 1/750000 - therefore* it is more likely that you will be hit by lightning 150,641,541 times.

What about difficulty adjustments though? Difficulty will increase by a factor of 4 every 2016 blocks. Current difficulty is > 32000 or 2^15, plus the implied 32 bits for an actual value of 2^47, ie 47 bits of zeroes at the front of the hash. We add 2 more zeroes every 2016 blocks, so after 105 such adjustments, the target will be all zeroes!

However, I peeked at the code, and even an all-zero target can be met with an all-zero hash. So theymos is right, Mr Lucky (who I think has an infinitely fast computer in his pocket) can go all the way, as fast as the net can broadcast blocks.

Rumor has it he stole an Infinite Improbability Drive.

Well, that would make this whole situation highly probable, then. Every time he turned it on.

He'd get them as fast as his client can write blocks to the disk.
Difficulty adjustments would be irrelevant, so would network latency be since the network would just slowly catch up after the fact.

Difficulty adjustments would be relevant to the calculations of just how lucky he is, but wouldn't have any affect on how fast he would obtain all the remaining coins.

Hmmm...

Thinking a little more, Mr. Lucky will have some coding to do.  Blocks are indexed based on their hash, so when he generates that second all-zero hash he's going to have trouble with the current implementation.  Actually, he'll have trouble before then, because if the target is low enough there won't be enough unique hashes...

(and before somebody asks: YES, there is a very small chance that two blocks will be found with the same hash.  And NO, that is NOT a problem that needs to be solved, it is so improbable it is not worth worrying about).

Technically, he wouldn't have to code anything. He could just run...

Code:
sh /dev/urandom

... and it would do all the coding for him.

ahahaha!

But maybe Mr Lucky would have more fun stealing bitcoins than generating them.
Same piece of code though...

Very true, since he could find all the private keys that have any BTC associated with them.

Code:
gim $ sh /dev/urandom
/dev/urandom: /dev/urandom: cannot execute binary file

For sure, I'm not Mr Lucky.

Strange kind of lottery.

./dev/urandom might be faster and more efficient than sh /dev/urandom.

(Or should that be exec /dev/urandom? I have been awake too long.)

I am not entirely convinced his dying of radiation poisoning would be the best possible outcome, since obviously that would, rather, be for a glitch in his system to cause him to generate for me instead of for him(*). So actually sorry he would earn no bitcoins other than however many I decide to tip him for grabbing me all the bitcoins.

(*) Plus the hashes when decoded correctly would be some awesome insight or immortality formula or something...

Mr. Lucky may be inclined to give away all of his bitcoin because he already wins all lotteries.  Including the fake international lotteries you get in your spam folder.  Not to mention he knows all government secrets, can read everyone's emails, and listen to everyone's skype conversations.

Good Old Benjamin Franklin learned how to decrease those odds.  Grin
