The last time I wrote about crypto mining on AWS we were still before “The Merge” — the (in)famous 2022 event when Ethereum switched from Proof of Work to Proof of Stake which spelled the end of ETH mining. The lucky people with free AWS accounts then switched to mining Ethereum Classic (ETC) or Ethereum POW (ETHW) but these were very unprofitable, yielding perhaps 10% or 20% max on a good day. And that’s not 20% profit, that’s getting $20 in crypto for $100 spent in AWS costs. Not a good deal.
Eventually it turned out that some other crypto coins became a little more profitable — Ravencoin (RVN) leading the pack, with Ergo (ERG) not far behind, followed by Ethereum Classic (ETC), Kaspa (KAS) and others. They still weren’t profitable to mine, but if you access to a discounted or free AWS account it may have worked.
