Btw, banks will flag multiple transactions of $9,999 even if the reporting threshold is $10k USD. Structuring to avoid the $10k reporting requirement is well known and no guarantee of remaining under the radar.

I hear this a lot but I don’t put any confidence behind it. This argument suggests that one day we’ll be able to brute force into lost wallets when we can break the encryption. Who knows how far in the future that will be.

But if I recall correctly, Bitcoin’s protocol is consensus driven. If there is an imminent threat of quantum computing, the developers could just improve the code base to resist it. Or fork the protocol to one that is resistant (Bitcoin 2). Then it’s up to 51% of the Bitcoin node operators to adopt the protocol. As soon as 51% of them upgrades, you immediately stop the threat.

I think the only reason Bitcoin is around is for two reasons: speculation, or the persons that actually believe it’s decentralised hard money free from control. I’d like to believe that there are a ton of people out there that run the BTC nodes to keep it decentralised. If there is an update that will resist quantum computing, I’m sure they’ll be eager to immediately upgrade their nodes and secure the network and those wallets. At least that’s how I believe it works, it’s been years since I first began researching it.

As an aside,
Bitcoin isn’t for me because I hate the environment impact. I hope one day it will become green, because it’s never going to go away. But I don’t blame the people that believe in it. In a world where the rich own everything and control the rules, these people are trying to opt out I guess - use a form of money that can’t be easily controlled or censored. Granted it’s all based on speculation, and whenever we run out of Bitcoin is probably when the system will become useless. Spending is discouraged when you run out of coins, so I don’t know how the Bitcoiners defend that argument. So definitely not for me.

Edit, on mobile so fixed some typos and clarified the 51% attack.

This sounds fishy.

What if somebody found out the private key for those accounts? Like, brute forced them?

Is it even technologically possible?

Somebody found their missing hard drive

Bitcoin private keys are 256 bit long. That means, there are 115792089237316195423570985008687907853269984665640564039457584007913129639936 (1.15*10^77) possible private keys.

Say you are using a bitcoin miner that's roughly 4x as fast as the curretly fastest one at 1PH/s (1*10^15), they you'll need roughly 1*10^62 seconds or 3*10^54 years.

Lets say you got a million of these miners, then you are down to 3*10^48 years, or 2*10^38 times as long as the universe has existed.

I was going to calculate how much electricity this would consume and how expensive it would be, but the answer to that is plainly "too much to imagine".

Not even that close. They'll flag any recurring fairly large transactions under 10k.

Purely hypothetically speaking, but, what if someone had their own private Dyson Sphere generating electricity? (Asking for a friend.)

This is correct for a given transaction, but there's no consensus needed to open a Bitcoin wallet. That is usually just a private key in an encrypted envelope.

Silk road

Maybe because I'm high, but you just made me ugly laugh on the bus. I just saw fireworks. And now I'm remembering that plan I had to go back to the early 90s, and buy stock in yahoo. But through a telephone error, I ended up buying cases of yoohoo instead. Still worth it. I got to go back in time and see a micheal jackson concert when he was still black, and a Nirvana concert back before they were heard of.

Still though.....to be a billionaire.

I'm unfamiliar as I've never had such. What counts as re-occuring? Is two payments always considered re-occuring?

If he made the Silk Road mostly to kickstart BTC, after buying a pile of BTC, and then waited till now to sell it - then he's kinda smart.

Sizable inactive accounts that wake up after years of dormancy draw investor attention because of the potential market impact if those coins are sold.

It would make me very happy if they liquidated and destroyed the market overnight.

Sounds like you need another visit from Doc Brown. I heard he'll come visit, if you give him first pick of your trash
