2630 entries / 259 threads
Litecoin copied Bitcoin's code, swapped its proof-of-work and rescaled three figures by four, then its creator divested his entire holding, citing his own influence over the price.
Trolololo opens a BitcoinTalk thread fitting a logarithmic curve to Bitcoin's price. He later rewrote the opening post; the 2014 chart and formula survive in the thread's fourth post.
Vitalik Buterin's BitcoinTalk announcement of Ethereum on the Altcoins board, January 23, 2014. The principal Bitcoin-community-facing record of the Ethereum whitepaper publication.
R2D221 opens the thread in 2014: why is the base unit called a satoshi? Did Satoshi choose the name, or did others start using it in his honor?
Adam Back introduces himself on BitcoinTalk as the inventor of hashcash, the mining function, says he believes he got b-money added to Satoshi's paper in 2008, and that he owns not a single bitcoin.

tardo opens the thread: is bitcent the official term for a hundredth of a bitcoin, and won't people rather buy 100 bitcents than 1 bitcoin?
Gavin Andresen tells the forum he will present Bitcoin at CIA headquarters in June, explains why he accepted, and discloses the $3,000 fee, posting it openly to head off conspiracy theories.
Kolbas opens the thread: time for a smaller unit, 1/100 or 1/1000 of a bitcoin, perhaps called a bitcent, before prices read 0,0251 BTC.
Satoshi's code had a COIN and a CENT and nothing smaller with a name. Bitcoin's smallest unit, the satoshi, was named by users on BitcoinTalk two months after his last post.
goblin opens the thread: one bitcent is now worth more than a US cent, so it is time to move the decimal point and make bitcoin more divisible.
