It would require 59,375 Bitmain U1's (released 2014) to generate the same amount of hashrate as a Bitmain S19 (released 2020). Running this many U1's would also use 118,750 watts, compared to the S19's power consumption of only 3,250 watts.

In November 2013, the first batch of Bitmain S1 miners were sold on BitcoinTalk.org, by auction, with a starting price of 1 BTC each. Only 20 units were available. The highest bid was 5 BTC, or ~$4,000 USD (As of July 2022, with the current Bitcoin price being $20,000, this would be $100,000).

The top 10 coins, by market cap, at the time of the Bitmain S1 auction in November 2013, were Bitcoin, Litecoin, XRP, Peercoin, Namecoin, BitShares, Feathercoin, Novacoin, Primecoin, and WorldCoin. Only 3 of these coins are still around today, including Bitcoin, Litecoin, and XRP.

Satoshi Nakamoto, the pseudonymous creator of Bitcoin, embedded a message into the first Bitcoin block, often refered to as the Genesis Block, ever to be mined. The message reads:

The Times 03/Jan/2009 Chancellor on brink of second bailout for banks

The first peer-to-peer Bitcoin transaction was from Satoshi Nakamoto to Hal Finney, only 8 days after the Genesis Block was mined. As a test, Satoshi sent Hal 10 BTC.

On May 22nd, 2010, Laszlo Hanyecz agreed to pay 10,000 Bitcoin for two Papa John's pizzas. At the time, 10,000 Bitcoin was worth only $41. As of July 2022, with the current Bitcoin price being $20,000, this amounts to $200,000,000.

It would require 1,055,555 RTX 3080 GPU's (commonly used for ETH mining, released 2020) to generate the same amount of hashrate as a Bitmain S19 (released 2020). Running this many RTX 3080's would also use 232,222,100 watts, compared to the S19's power consumption of only 3,250 watts.
