That is a question which also has the answer in itself if you look at the data,miners made a lot of money in such times and they,the winners did not start mining when crypto reached these new all time highs,they were mining a whole long before this happened.In this time the "losers" started to appear in the market making the prices of video cards skyrocket to never seen before levels and by "losers" I mean the people who came in after they saw the new all time high and they were in for a quick buck.It is exactly these persons who lost the more and sold everything they bought at a loss because mining is not for a quick buck but is a long process that in the end rewards the patient ones who believe firmly in the future of crypto.
