Bitcoin mining machines are one way to obtain bitcoins. Bitcoin is an online virtual currency created by open-source peer-to-peer software. Instead of being issued by a specific currency institution, and produced by the massive computation of a specific algorithm, the Bitcoin economy uses a distributed database of nodes throughout the P2P network to identify and record all transactions. The decentralized nature and algorithm of P2P can ensure that it is impossible to artificially manipulate the value of bitcoin by producing a large number of coins.
Any computer can become a mining machine, but the returns will be low, and it may not mine a single bitcoin in a decade. Many companies have developed specialized Bitcoin mining machines with special mining chips that are tens or hundreds of times faster than normal computers.
Currency system by the user (the user through the key control wallet), trade (trade will be broadcast to the whole currency network) and miners (generated by competition calculation agreed on each node of the chain block, block chain is a distributed public authority books, contains the currency network of all the transactions happened) Bitcoin Mining Machine,Antminer S19j Pro,bitcoin Miner,btc mining machine,S19 Pro Hyd Shenzhen YLHM Technology Co., Ltd. , https://www.ylhm-tech.com

4. FAQS- evaporative air cooler
(1) How does an Evaporative Air Cooler work?
Evaporative Air Cooler cools the air by means of the evaporation of water. When water evaporates into the air, the result is a mixture of air and water molecules. This chemical change requires heat, thus energy or latent heat is taken from the air molecules - dropping the actual temperature of the air.
(2)Whether the Air Cooler can be used in enclosed spaces or not?
It must be kept level and there must be water in the tank. The room should have doors and windows opened to allow free air flow. Best scenario is for the Air Cooler to be placed near an open window from which the fresh air flows through the Air Cooler, which circulates the air, which then leaves via the door.
(3)What are the differences between air coolers and air conditions?
The Evaporative Air Cooler is not an air conditioner as it does not use a compressor or refrigerant gas. It should not be expected to cool to the same degree as a refrigerated air conditioner. It works best in hot and dry conditions.

Bitcoin miners manage the Bitcoin network by solving the problem of proof-of-work mechanisms with a certain amount of work -- confirming transactions and preventing double payments. Because hashing is irreversible, finding the number of random adjustments required to match is difficult, requiring a trial-and-error process that can predict the total number of times. This is where the proof-of-work mechanism comes into play. When a node finds a solution that matches the requirement, it can broadcast its result to the whole network. Other nodes can then receive the newly solved data block and check whether it matches the rule. If the other nodes calculate the hash value and find that the requirement (the operation goal required by Bitcoin) is satisfied, then the data block is valid and the other nodes accept the data block.
