Not sure what was the price in March, I was eyeing a card in 20k range and was disappointed with launch price of 3060/3070 but since then we all know the story.
This mining craze can only go down if profit drops thats the only solution at this point in time. For new cards with LHR lets hope it works and not get cracked like first attempt from nvidia
It is as he might have purchased those cards at low rate that what it is now so
Selling price - 90k
Purchase price - somewhere around 70~75k (assumption)
Mining profit - not sure but say 1L?? Miners can confirm
So in couple of months he made good profit, not bad at all and selling them when there is high demand
