I mined LTC and a few other scrypt coins back in 2013-2014 using a small GPU based farm and am now thinking about jumping back into mining after a few years off; is it nucking futs to want to rock a GPU farm for a few solves again, or has the supremacy of ASIC's really made this insane to consider even IF I had a zero cost power solution?
What says you, bitcointalk?
Unless you have the current or even a few year old gpus ready to go this is a bad time to try to get back in to gpu mining. There IS still lots to mine though. The market has pushed Most of the equipment for gpu mining to 3x and 4x prices. Cards that would sell on ebay for 150usd are selling for 600 usd. No joke.
If the market just goes sidewise Right now even those 600 dollar 8gig rx580s on ebay ROI will payoff in 4-6 months. ETH is the common big gpu coin to mine atm. Could change with proof of stake(not a idea I like) switch over with no solid date on that. With 8,000 other alt coins Something will become profitable if ETH becomes Not profitable.
If you have zero cost electricity then pin down a Now over priced bitcoin ASIC from 3 or 4 years ago The s9s make money again. My learning s9 asic I bought in nov 2020 for 65 usd has paid for itself 10x already. (its at a free power location) 300usd for a s9 is not unreasonable 600 I wouldn't buy.
