Do you think it will be ok to order a batch of video cards from China for mining ?
Yeah sure and it is the best time to buy cheap used GPU´s. 3060 12GB for $120 or so is a good choice (3070 for $160, 3070ti $200 or HX70 for $120....). The RTX30x0 series are better for mem intensive algo. Avoid the RTX40x0 series, too expensive for the hashrates.
Also AMD cards getting cheaper and cheaper.
