RE: Warren Buffett thinks Bitcoin is of no use

my problem with bitcoin begins and ends with .. wasted energy.

their process requires incredible amount of wasted energy to find that magic number

in reading about them defending themselves.. i think I am more appalled at the numbers..

Bitcoin energy consumption on the world electrical grid is just 247 TWh (0.16%)

tenth of the world's energy supply just to facilitate transactions?

electric companies love bitcoin
