LED umbrellas can be used in rainy days. In addition to blocking the wind and rain, this umbrella is also equipped with LED lights, which can be warmed up in the rainy night. Of course, you can use it in the night without rain, adding a little fun. 
The umbrella is called the Silver Wing Killer LED Umbrella. The LED light of the handle is available in white and blue. The battery is priced at $24.99 (about 154 RMB). 
Litecoin mining is the process of validating transactions in the blockchain, closing the block, and opening a new one. Litecoin uses the proof-of-work consensus mechanism, which uses computational power to solve the nonce, which is part of the hash, that secures the block. The hash is the alphanumeric sequence of numbers that is encrypted by the hashing algorithm. When the nonce is solved, Litecoin is rewarded.
Litecoin mining became popular in 2011 when Charlie Lee, a software engineer at Google, announced its creation as a Bitcoin fork with modifications intended to help it scale more effectively.
Just like Bitcoin, it can be mined on computers using central processing units and graphics processing units. However, it isn't as profitable or competitive as purchasing an application-specific integrated circuit (ASIC) and joining a mining pool.
