is it safe to buy new secondhand miners cause i have serious health issues touching packages from dirty warehouses ?
I guess you are safe. Before you unpack the miner in the box, you can spray disinfectant and dry it in the sun before using the miner. Do not feel too paranoid about the covid because you should not worry about it as long as you can be careful.
just alcohol are enough mate , spray them thoroughly or consecutively . i have health issue also so all my online deliveries make sure being alcohol sprayed .
