The Dogecoin (DOGE) and Litecoin (LTC) mining equipment, code-named LD4,  has been updated and launched by the cryptocurrency mining business BIT  Mining.

The company’s LD series of ASIC mining rigs, which are optimized for the  DOGE and LTC blockchains, is already in use by BIT Mining. They are  energy-efficient and give high hash rates.

The LD4 has undergone several trials and tests, and the results of these  trials and tests were utilized to enhance and tweak the design.
