I analyzed Gavin Andresen’s faucet transactions. Here’s how many 5 BTC payouts are unspent

I was curious about Gavin Andresen's famous Bitcoin faucet from 2010, when anyone could claim 5 BTC for free with just a captcha. I decided to take a closer look at those transactions and see how many of those outputs still exist today.

Here's what I found:

• 2,471 payouts (5 BTC each) were created by Gavin's faucet

• Out of those, 779 remain unspent (still sitting in the UTXO set)

• That totals 3,895 BTC, which is about 31.53% of all the 5 BTC payouts

Important notes:

• I only counted the faucet payouts of 5 BTC each. The later payouts of 0.5 BTC and smaller are not included.

• By 'unspent' I mean outputs (UTXOs) that have never been spent since they were created in the faucet transactions.

It's very likely that many of these (if not all) are permanently lost. Back then, people often didn't back up their wallets or simply forgot about them, since 5 BTC was worth almost nothing at the time.
