Hey everyone. I have been interested in mining for the past few months but have only recently gotten serious about starting with it. When I looked for good GPU's for mining Ethereum I noticed they were out of took almost worldwide. RX 470's are selling secondhand for like 400 dollars Even the alternatives like 5XX series is out of stock. Any ideas when all the mining GPU's will be back in stock.
Or is it not worth the wait and am I better off just buying Nvidia cards and mining other crypto?

Thanks in advance
