Am 28. November 2012 hat Bitcoin seine eigene Blockbelohnung halbiert – von 50 auf 25 BTC –, gemäß einem Zeitplan, der schon Jahre zuvor in den Code geschrieben wurde. So sah das erste Halving aus, warum es existiert und wo der Zeitplan heute steht.
Was ein Halving ist
Neu
kommt in den Umlauf als Belohnung für die Miner, die Blöcke zur Kette hinzufügen. Nach jeweils 210.000 Blöcken halbiert sich diese Belohnung. Bei etwa 10 Minuten pro Block ergibt das ungefähr alle vier Jahre.
Das kann man in der Funktion GetBlockSubsidy von Bitcoin Core sehen. Die Belohnung startet bei 50 BTC und halbiert sich alle nSubsidyHalvingInterval-Blöcke, einem Wert, der auf 210.000 festgelegt ist. Ein Kommentar im Code sagt, dass es „ungefähr alle 4 Jahre“ passieren wird.

In October 2013, the FBI made its first-ever bitcoin seizure, and within days the internet had found the wallet and started leaving it messages. Here's how that fight over nearly a quarter-million $BTC ended with a pardon, the US Strategic Bitcoin Reserve and billions of dollars in coins.
What Silk Road Was
Silk Road was a hidden marketplace on Tor where users bought and sold illegal drugs and other unlawful goods, paying in bitcoin. Prosecutors say it ran from January 2011 to October 2013. The government's complaint alleged more than 9.5 million BTC in sales (about $1.2B at the time) and more than 600,000 BTC in commissions for the operator, known as "Dread Pirate Roberts."
The Takedown: Oct 1-2, 2013
On October 1, 2013, federal agents arrested Ross Ulbricht in San Francisco. He was at the Glen Park branch of the public library, using a laptop, and agents seized it on the spot. They searched his home the same day. The site went dark right after.
The Wallet Everyone Found
Bitcoin is a public ledger, so it didn't take long for people to spot it. On October 4, Ars Technica reported that users had found an address, tagged "Silkroad Seized Coins" on Blockchain.info, holding 27,365.88 BTC. Its first deposit came on Oct 2 at 10:12 GMT: 1,000 BTC from 47 different wallets, about 15 hours after the arrest.
An FBI spokesperson told Ars the bureau had seized "more than 26,000" bitcoins, its first bitcoin seizure ever. She said she was "not able to confirm" that this particular address was the government's. The DOJ later put the server haul at about 29,655 BTC.
The Trolling
People started sending tiny amounts of BTC to the address, each with a "Public Note" attached. Some were protest messages about drug policy and Ulbricht, and plenty were plain insults. Every one is still on-chain. A Bitcoin researcher Ars spoke to summed it up: even the federal government couldn't keep its transactions secret.
The Bigger Stash: 144,336 BTC
On October 25, 2013, prosecutors said agents had recovered a wallet with about 144,336 BTC from Ulbricht's laptop and other hardware. That brought the Silk Road total to about 173,991 BTC, then worth over $33.6M. The FBI called it the largest bitcoin seizure ever at the time.
The US Marshals Auctions (2014-2015)
The government then sold the coins in four auctions:
June 27, 2014: 29,656.51 BTC from the Silk Road servers, in 10 blocks. Venture capitalist Tim Draper won every block. His price was never disclosed.
December 2014: 50,000 BTC from Ulbricht's hardware. A syndicate led by SecondMarket and Bitcoin Investment Trust took 48,000, and Draper took 2,000.March 2015: another 50,000 BTC, split among three winners (27,000 / 20,000 / 3,000; itBit was the 3,000 buyer).November 2015: the final 44,341 BTC, split among four winners.
At $82,547.50 per BTC, Draper's June 2014 haul alone would be worth about $2.45B today.
Conviction, Life Sentence, Pardon
In February 2015, a federal jury in Manhattan convicted Ulbricht on all seven counts after a four-week trial. On May 29, 2015, Judge Katherine Forrest sentenced him to life in prison and ordered him to forfeit $183,961,921. On January 21, 2025, President Trump granted him a full and unconditional pardon.
"Individual X" and 69,370 BTC
In November 2020, the DOJ filed to forfeit about 69,370 BTC, worth roughly $1B at the time. According to the complaint, a hacker it called "Individual X" took the coins from Silk Road years earlier and never spent them. On November 3, 2020, Individual X signed them over to the government. Ulbricht later settled and agreed to the forfeiture, and the Ninth Circuit finalized it in December 2023. A judge then cleared the way for a sale on December 30, 2024. As of January 2025, Protos reported the coins were still in the government wallet.
What Happened Next
On March 6, 2025, an executive order created the US Strategic Bitcoin Reserve. It's funded with BTC the Treasury has finally forfeited, and the order says bitcoin deposited there "shall not be sold." There's no official public breakdown showing exactly where the Silk Road coins sit today, so treat any claim about that with care.
What Those Coins Would Be Worth Today
At $82,547.50 per BTC (Binance BTC/USDT, Oct 8, 2026, 14:13 UTC):
27,365.88 BTC (the trolled address): ~$2.26B144,336 BTC (Ulbricht's wallet): ~$11.9B
173,991 BTC (total 2013 seizures): ~$14.4B69,370 BTC (Individual X): ~$5.73B
The Takeaway
Bitcoin gave the trolls a public megaphone and gave investigators a permanent trail. Everything in this story happened on a public ledger: the seizure, the trolling, the auctions and the Individual X coins. Bitcoin is pseudonymous, not anonymous. Once an address is linked to a person, its whole history is visible to anyone. Self-custody and privacy are worth having, but they take real discipline.
Where do you stand on this: is on-chain transparency Bitcoin's best feature or its biggest weakness?
