Curiously, after hitting a random page and >> twice, I came upon this page https://playxo.com/bitcoin/904625697166532776746648320380374... that had several keys in use in the past. I would expect this website, in the rare event of discovering some positive balance, to try spending it right away...

Why a thief? Bitcoin is a silly idea based on scarcity that doesn't exist. If someone generated the right numbers by chance and had luck, I wouldn't say they'd be doing anything wrong getting whatever is there. It's not the same as stealing data, and is not the same as hacking into a banking system. It's decentralized, and there isn't the concept of real scarcity. It's not even hacking. https://henvic.dev/posts/bitco…

My father always said, if you find something, and it isn't yours, it belongs to someone else. There are actual laws in the US that if you find money, you are supposed to report it to the authorities, and if no one reports losing the money in some fixed time (30 days?) then you keep it.

Get real. You're not getting anyone's property if you discover a private key by accident that that a distributed blockchain with no owner accepts to transfer a token in a virtual wallet like that. We're talking about something non-fungible and not scarce.

Bitcoin's supposedly scarcity is a joke that doesn't make any sense whatsoever.

It is a far lower number. Are you checking random pages or browsing from the beginning? If you check random pages you're unlikely to even find a single page with a tx.

Started at random point and then clicked next. I checked a dozen or so and most had around 5-8 orange addresses each. Maybe I just hit a range that is especially busy. Which in a way is even more ominous though since it should be random

what range? i feel you're joshin'

Am I right in understanding that this is somehow checking every private key on the page against every single wallet with money? How can it do that so fast?

It derives the public keys from the private keys and then check these.

Thanks. So each of these potential private keys that show up on a page would only have one corresponding public key? I guess I forgot how basic private/public key encryption works (again).

I get that it's statistically impossible to actually rob bitcoin using this site (by finding a "green" private key).

But can anyone explain why I am able to find so many "yellow" ones (empty wallets that have previously made transactions)?

I expected going in to _only_ find "red" (never used) wallets and was surprised to find that was very much not the case.

It's like passively playing the world's worst lottery in terms of odds, but hundreds of thousands of times every second. It's fun but the odds are astronomically low. I have a script[1] that generates a pub+private key and checks against a massive file of addresses with BTC[2]. The list of addresses is loaded in memory as a python `set` so checking is O(1), but I feel like optimisations at increasing the rate are fut…

What's wrong with explicitly closing it though?

It is not 1/2^256. It is "number of wallets with balance"/2^256.

actually its "number of wallets with balance"/2^160. You don't need to find a specific private key, anyone will do that yields a public key that hashes to the BTC address.

A quick search shows there are a little over 30M addresses with a nonzero balance, which is just under 2^25.

That means the actual probability would be about 1/(2^135).

At a million hashes per second, that means you would likely find one after about 10^27 years.

> Finding an active wallet is hard, but not impossible. Every time you open a random page, you have a chance of finding someone else's fortune. Good to know I have a 1/2^256 chance to find a bitcoin billionaire's wallet. This feels only slightly more ludicrous than the guy who lost his bitcoin in a hard drive and went looking for it in a dumpster.

I have had a crappy life, abused sexually and physically when a child, but trust me whenever I re-hear about that guy losing his hard drive with BTC in it, I am like, yikes.

I've had both, and I'd promptly forget about the bitcoins for the ability to have lived an un-fucked life (which would pay for itself more readily too).
