The Trend is over. Last Year we have seen huge demand of cards that is used for crypto mining. But now the hype is gone. Cards become cheap and yet people are not interested to have it.
that's because crypto mining is not profitable now. Due to decline of price of coins people are no longer see profit and they are in loss after paying electricity bills.
One of my friends has 6 cards He bought last year and already took his investment. The room becomes too hot and also noisy. He bought AC for that. However He was able to mine less than 1 ETH per month. At that time ETH was 800$ then 1000$ almost.
But now if he run these cards no longer profitable only 300 $ per month. He posted ads for sell his cards. But not good response from people.
He is totally stop now he will begin again if we see green market.
I am agreed with your article as last time that happened.
