"Hey guys, looking to get a new Ethereum miner for some mining action. I'm open to both new and used rigs, but preference is for something with a decent hash rate that's under $500. DM me if you've got a deal to share"
"Hey OP, I've got a used RX 580 rig that's been running 24/7 on ETH for the past year. It's been churning out around 25Mh/s. Hit me up if you're interested."
"Hey OP, got a RX 5700 XT that I'd consider selling for mining ETH. Not sure if it's enough to compete with newer rigs, but should still pull in some decent earnings. Interested in a decent price, though - not looking to lose my shirt on it"
"Hey OP, I've got a used Bitmain S19 Pro that I'm willing to let go for $3,800. It's been well-maintained and has a hash rate of 110 TH/s. PM me if you're interested!"
"Hey OP, I've got a used GTX 1060 Ti that's been tweaked for mining ETH. I'm looking to sell it for $200 OBO, let me know if you're interested. It's been doing around 20 MH/s on the Ethash algo."
"Hey OP, I actually have an RX 6800 XT that I was using to mine but switched to GPU gaming instead. It's still got a good hashrate for mining ETH, would you be interested in buying it?"
"Hey OP, I've got a used Radeon RX 480 that I've been running with my Ethereum rig, it's not the most powerful miner but it's still got some life left in it. PM me if you're interested, I'm looking to get rid of it for a decent price."
"Dude, I've got an old RX 470 that was being used for mining, but sold my rig last year. It's in decent condition and might be worth a mention - not sure how much it's worth in the current market. PM me if you're still looking for something."
"Hey OP, I've got a GTX 1070 with a custom rig that can do around 25 MH/s Ethereum mining. It's a few years old but still works great, and I'm open to negotiations. DM me if you're interested."
"Hey OP! I've got a RX 6700 XT GPU that I've been using for mining, but it's been a while since I've run any Eth miners myself. Would be willing to sell it to someone who needs it, PM me for details"
"Hey OP, I've got an AMD RX 6800 XT lying around that I think would be a decent Ethereum miner. If you're interested in a GPU-only setup, I'd be down to part with it for a pretty penny."
"Hey OP, actually got a 5800X Ethereum miner that's been collecting dust. It's not the most powerful rig out there, but still gets some decent hashrates. PM me for the details, $400 OBO."
