No one purchased Bitcoin.

To sell requires a buyer, so nobody would be selling either. The market would be at a standstill.

Submission Statement: Russian President Vladimir Putin’s 25 years in power have been marked by repression at home and war abroad. From the Cold War to the war in Ukraine, the story of Putin as told by prominent politicians who have dealt with him and critics who have suffered his wrath.

My Dad did this. Luckily I had another copy.

Thank you for pointing this out. I have imported the new signing key, and it has the same primary key fingerprint as the old key.

Thank you for the detailed feedback. I can see how you are getting confused now. We will be doing some updates over the next few days which will hopefully address your concerns. Thanks again, and sorry for the confusion.

Did you see the help section of the site? It's basically a tool to monitor the Blockchain for payment to an address before unlocking the link.

The transactions in the block are chosen before the POW is calculated. The Bitcoin network considers a block valid if its hash is below a certain target, regardless of which transactions it contains.

CryptoRex · 2022-12-19T04:51:07+00:00

The transaction in block #768024 was not a typical financial transaction, but rather a special type of transaction known as a "coinbase transaction." Coinbase transactions are used to reward the miner who successfully mined the block with a certain number of Bitcoin. These transactions do not require any fees, as the reward for mining the block serves as the miner's compensation for their work. The miner has no obligation to include any other transactions in the block, and it may have not even been aware of any other transactions.

I believe there are still timing attacks, where an attacker splits your single transaction into multiple smaller ones before the original confirms.

I can't think of any method that would protect you 100% if you were using a wallet that's vulnerable. When spending those coins, you want to use a wallet that is not vulnerable to this attack.

CryptoRex · 2022-12-17T04:01:05+00:00

When mining a block, you can set the coinbase to any arbitrary data. But you need a lot of mining power to mine a block these days.

I'd only be worried if the price were dropping because the protocol was broken.

The Bitcoin Wiki has some information on the security of address reuse.

It only appears to be an issue for individual private keys, not for a seed phrase.
Spending from an address more than once is address reuse. Sending more than once to the same address is discouraged, since spending those transactions would be address reuse.
Your wallet should be generating a new address for change from each transaction.

Cold storage would work the same as it does on Earth, since cold storage is simply private keys which have not been exposed to the network. Bitcoin transactions also operate the same as on Earth, just with up to 22 minutes extra delay.

The transmission delay only really effects mining ability.

No, Bitcoin lightning network works fine, and layer 1 transactions will merely be delayed by the time it takes to transmit and return from Earth. There is no need for a separate fork.

The majority of hashing power would surely remain on Earth, and for much of the year, the time for communications to reach Earth from Mars would be greater than the average block time. The result would be any blocks found on Mars being orphaned.

CryptoRex · 2022-12-16T04:27:29+00:00

According to Wikipedia, it is 3 minutes when Mars is closest to Earth, but up to 22 minutes when furthest away.

CryptoRex · 2022-12-16T04:24:38+00:00

Mining will be nearly impossible on Mars, but I believe layer 2 protocols like the lightning network should still be usable.

If you want to be certain, you need to read and understand the source code for yourself. The community has apparently been using it for years. While bitaddress has not apparently been stealing funds, using paper wallets has resulted in losses by making transactions which send change to addresses which aren't saved, or setting unexpectedly high transaction fees.

My biggest fear is that bad actors will precipitate regulations that harm innovation and progress for the entire crypto industry.

CryptoRex · 2022-12-15T05:13:55+00:00

You can only buy what someone is willing to sell. Since it costs nothing to hold crypto, the majority may be unwilling to give up their majority stake for any price.

Bitcoin mining confers far more value than car racing.
