As some of you already know, peoples are using graphic cards to mining ethereum (a cryptocurrency) and thats also why they take every available card, they actually invest to bought more card and make more ethereum again and again and again ... but now the value of ethereum is as low as a car pimped by xzibit ... and that why we see some used series30 slowly appear, they are quitting the boat before it sink and try to make the most they can. Sooo if you can wait a couple day, i think we going to see some good deal by people who are afraid to being stuck with the card they overpaid, i actually need one too but i wait and try to help the market a little .. aniways maybe i’m allll wrong but i think that can be helpful to know that 🤷‍♂️ (I’m french, sorry if my english is not that good)

Yes but they are too much mining the same product so the value of ethereum just not worth it anymore look on the facebook marketplace, they already try to sell quick before everyone do the same and the price drop

What are you talking about?  Have you looked at the value of ETH?  It's value is at an all-time high.  Have you looked at the mining profitability?  It is very profitable.

Maybe i’m wrong like i said but the ethereum is actually dropping and i see some series 30 near the place i live at 1000$ Appro.

Ok i do some research and the problems is more about mining if i understand right that wasn’t suppose to be a thing at first but i’m french so if you want to check by yourself that can help me no doubt

Bitcoin has dropped 12% in an hour.  Has it started to happen?  Have you somehow forecast the bubble bursting?  That would be exciting.

All the information you provided was very wrong or misleading (like, you think a $330 video card selling for $1100 is an indicator of video cards becoming cheaper?!), so I have a hard time accepting a non-explanation about your suspicion.

Ironically, in the short-term, big fluctuations create a big jump in mining profitability, since a large amount of buys or sells create a lot of cryptocurrency network load and bigger transaction fees paid to miners. It's only long-term value slumps which negatively affect mining.

Because of this upset, mining profitability is up something like 30% right now in the short-term.

I like the optimism, but Ethereum mining isn't going away until they switch to Proof-of-Stake.
Then the question will be how other Proof-of-Work coins are doing.
