Hi Steemit Readers,
Never ever use laptop for mining that will make your laptop condition worst, basically mining means solving mathematical problems which can be solved with GPU/CPU(Past)/ASICs(Present) power.
Mining is done with specialized hardware called Application-specific integrated circuit chips (ASICs) which are trillions times more efficient than laptops.
ASIC machines mine at unprecedented speeds while consuming much less power than FPGA or GPU mining rigs.
