You might also want to buy a Bitcoin mining machine like this

A few days ago, I received a charge notification on my phone saying that my credit card was charged $400, and Amazon also told me that the 21 Bitcoin computer I ordered was on its way to my door.

The 21 Bitcoin Computer is basically a Raspberry Pi connected to a custom Bitcoin mining ASIC and a heat sink, but it's one of the most interesting Bitcoin mining machines in recent years. While you can easily build one yourself, the fact that 21 is developing them and selling them for hundreds of dollars just shows how promising the future of Bitcoin systems is.

Is the 21 Bitcoin Computer worth the money? First, I also doubt that this machine will help me earn back the costs associated with purchasing and running it. Second, while the 21 Bitcoin Computer is cool, I don't think it's the kind of Bitcoin mining machine that we all want. Even so, I still think it's a very good proof of concept.

The 21 Bitcoin computer is basically a new version of a previously developed Raspberry Pi mining machine . I used a similar Bitcoin mining machine for two years and it really gave me a good experience. What's more, you can buy a Raspberry Pi computer for only $60 and let it "warm" your bedroom while making you a little money every week. Some people will say that they are not engaged in Bitcoin mining activities to make money, but to support the entire Bitcoin network.

The ultimate goal of 21 is to have something like this Bitcoin system built into every phone and computer. This would really change the way blockchains are handled, which would make for interesting changes in the entire ecosystem. But the fact is that this computer is similar to Baby's First Bitcoin mining machine, which is a plug-and-play device that is easy to understand and use, and is also a great way to learn the secrets of mining.

The device is designed to be a test bed for bitcoin-related activities, such as selling licensed digital products, renting out system time to bitcoin miners, and accepting bitcoin on commercial websites. Its core application is called "21" and runs from the command line. Typing "21 mine" activates the bitcoin miner, and other command lines activate various functions. You can also perform basic bitcoin functions through the server. For example, bitcoins can be provided through the text messaging system, which uses the Twilio system to send payment amounts. You can also send digital files on the server in the form of bitcoins .

So why use the 21 Bitcoin computer instead of some other lab bench? In the words of a Reddit user named " Tequila13 ", "The industry has this vision of the future of Bitcoin: every phone will have a 'mining chip' installed, and people will be willing to spend money to buy mining chips, and would rather lose money to mine for a better future. In the future, millions of people will buy phones with less battery life because they believe in the value of Bitcoin."

Although it's a bit utopian, the reality is that if there are millions of mini-miners driving the development of the entire Bitcoin network, then this will become a more interesting world: Bitcoin will flow faster and more securely, the transaction rate will remain stable, and the blockchain will become a force to be reckoned with in the financial industry. In short, it's like an "Internet of Money", just like early Internet servers, which are still quite limited in functionality at the moment, but suddenly one day someone will build a financial product equivalent to Google Docs in the browser.

The 21 Bitcoin computer is an experimental platform. It's definitely a smart move for the company and a great entry point to get a head start in the Bitcoin market. You could easily build this Bitcoin mining machine yourself, but without the proprietary software and server, I doubt you'd have the same out-of-the-box satisfaction. When I built my first Bitcoin mining machine, I spent days analyzing the various hardware components and software. To use the machine, I simply typed in "21 mining" and suddenly I was in the future of digital currency. That alone is probably worth $400.
