i wouldnt start going down the road of XXXm slithers of plastic. as the materials used in creating an asic actually outpace credit card plastic
did you know the power cord(to wall socket) alone has more plastic than 5 credit cards
the styrofoam/bubble wrap that the delivery box contains also has more plastic than credit cards
and i havnt even started on the insides of an asic
the main debate about bitcoins environmental wastage is myth busted because most asic farms are set up in area's that have cheap renewable electric generation, meaning low coal/oil/gas electric generation linked to bitcoin
however visa/mastercard's datacentres, wall streets skyscrapers and all those individual bank branches use far more electric
