me gusta esto ELI5 , que esplica el porque del mining :
21 is trying to develop a bitcoin powered micropayment ecosystem. These are tiny transactions with no fees (because you’re not going to pay a $0.02 fee to send someone $0.005). Most miners are not going to add these tiny 0 fee transactions to the blockchain. So by putting miners in their devices and controlling the mining power they are able to ensure that the blocks they find do include these transactions.

“Anyone who thinks this is about making money by mining has very little insight into what Bitcoin actually offers the world. This is not about bringing the old economy (banks, businesses, governments) into the Bitcoin family. This is about building entirely new economies, ones that have never and could never have existed before. 21inc can see the vision and they just bootstrapped the IoT on the Bitcoin blockchain. Thank your lucky stars on your way to the moon.” - PhiMinD
“I’m fairly sure this is NOT an end user device. This device appears to be solely for the purpose of prototyping integration with other devices, and allow people to work out the ends and outs of the process. My assumption is that in like 6 months to a year, a much more compact and integrated device will be released that would be far cheaper, and suitable for installation in actual consumer devices. This is for developers.” - DakotaChiliBeans
“The more I think about it, the more incredible and groundbreaking this seems. When every piece of hardware and software has the ability to transfer money, our entire concept of how we do everything changes. We’re only beginning to imagine the possibilities. Even the few simple ones I’ve been thinking of make my head spin. Bitcoin as a human currency is exciting. Creates a more open system, breaks monopoly, gives you the option of true, non-revocable ownership. All great stuff. But it’s these revolutionary ideas that make me believe that Bitcoin, or a successor very much like it, will take over the world. As someone invested in bitcoin, I’d like to see it succeed and my investment pay off, but goddamn will this be an exciting ride regardless. At this point, I’m seriously thinking of buying and developing on it. The potential here is lightyears beyond what most people are thinking.” - consideranon
“Seeing the 21 Bitcoin computer reminds me of the developer kits for oculus rift. It took a lot of time to perfect before going fully public. It was also tested with a pre-release through Samsung’s VR headset. Other more resourceful people bought the cardboard much like the same people would buy the Raspberry Pi instead of this. Anyway, the 21 computer is very likely the first iteration of many.” - Hiro_Y3
“I think it removes a step in the process. Instead of learning about wallets, private keys, maintaining a login and password, etc, the computer takes care of all of that without the user having to think about any of it. The mining function provides initial liquidity to get the ball rolling. This is the first step of payments being built into the IoT.” -TDBit
“Most of everybody here is missing the point. This is a bitcoin computer. This is not made to simply mine to generate a profit but rather a miner is just an added part. The miner is used to continuously supply the Bitcoin computer with bitcoin. It uses the bitcoin to “write” to the blockchain. It’s like a digital quill with an endless bitcoin inkwell.” -Fuzzypickles69
“Ok, this takes a leap of faith, but what they’re trying to do is build a full-stack device which can send/receive bitcoin and which also solves the “how do devices get bitcoin in the first place” problem. Imagine the whole thing being a lot smaller and cheaper, and embedded in lots of devices globally. Now you have a world in which millions of devices (machines) can send and receive tiny payments, and which natively have a currency unit to use for that purpose.” - melbustus
