You’ll need a Bitcoin wallet in which to keep your mined Bitcoins. Once you have a wallet, make sure to get your wallet address. It will be a long sequence of letters and numbers. Each wallet has a different way to get the public Bitcoin address, but most wallets are pretty straightforward about it. Notice that you’ll need your PUBLIC Bitcoin address and not your private key (which is like the secret password for your wallet).
Nor was it simply the deep pockets. At these prices, even smaller operators have been able to make real money running a few machines in home-based, under-the-radar mines. Take the 20-something Wenatchee man we’ll call “Benny”—he didn’t want to be identified—who last July bought three mining servers, set them up in his house (one in the master bedroom and two in the living room)—and began mining Ethereum, bitcoin’s closest cryptocurrency rival. As Ethereum climbed from $165 in July to nearly $1,200 in January, Benny had not only repaid his $7,000 investment but was making enough to pay his mortgage. As a side benefit, this winter, Benny’s power bill went down: The waste heat from the three churning servers kept the house at a toasty 78 degrees. “We actually have to open the windows,” he told me in January. His servers, meanwhile, pretty much run themselves—although, when he’s at work, clerking at a grocery, he monitors the machines, and the Ethereum price, on his phone. “It’s just basically free money,” Benny says. “All I have to do is wake up in the morning and make sure nothing crashed during the night.”
In January 2009, the bitcoin network was created when Nakamoto mined the first block of the chain, known as the genesis block. Embedded in the coinbase of this block was the following text: "The Times 03/Jan/2009 Chancellor on brink of second bailout for banks." This note has been interpreted as both a timestamp and a comment on the instability caused by fractional-reserve banking.:18
