a guy ran a code on laptop and generated bitcoins. he sold it for pennies beacuse he burnt the electricity for it.
so today miners burn electricity and sell the coins at $20k+ to cover the electricity cost.
and new inverstors see value in it and investors keeps growing.
lets say every human soul on this planet owns some bitcoin then who would buy. i will buy cos i want more of it coz greed played its part. and price will go up coz there are only finite bitcoins. and why do i want because its the borderless high liquidity money.
