Asic Bitmain Antminer X3 (220Kh) is powered by CryptoNight algorithm and Dynex changed the algorithm to DynexSolve at the end of 2022. If you are lucky enough to use Antminer X3 competently, then we are happy for you. But this is very difficult to guess and there are risks of mining a worthless coin.

Cryptonight coins? They are almost all dead 🤣😅🤣 the few ones that remain are Dero, Loki, havven, turtle coin, I mined cryptonight coins since 2017 and 90% of them died, it was a painful experience for me.

You should post this topic in the Altcoin Mining section, RandomX has nothing to do with BTC and SHA256.

I didn't find any mention to RandomX in your first link?
I only looked very briefly, maybe I'm wrong but I don't want to waste my time to be honest, I appreciate any form of reverse engineering but when it comes to RandomX it's still a big waste of time so far.

In my opinion you can't start with an ASIC SHA256 and make it mine RandomX which is ASIC-resistant as well.

A few years ago I was in contact with a guy from Russia. He was sending videos to all his contacts to show that he managed to mine RandomX with an Antminer X3 with a really impressive hashrate. He claimed to have modified the firmware, and show workers pages with crazy hashrate on MoneroOcean pool.

The reality was that it was a fake, that the guy was just editing videos and never made it. I think in real life he never really tried to be honest.
He disappeared overnight and then we found out from a third party that this guy was just using a huge amount of botnets, and he was trying to sell his so-called "custom firmware" for Antminer X3 to inexperienced newbies.

That's the whole point of RandomX, to be ASIC resistant, and if a flaw had been found, I think we'd all know about it.

PS : Goodluck to try to give motivation to developpers with a Bounty you don't even give the amount


Did anyone ever manage to get the X3 to mine cryptonight variants? CNv2 there was a similar video on YouTube showing something similar with the X3 mining XMR after it had changed algos before randomX

I imagine it was also fake?

DYNEXSOLVE IS THE ONLY CURRENT MINER FOR DYNEX COIN (DNX)--

There may be a coin in the past that you are confusing with Dynex Coin (DNX).  The DNX coin is in no way based on a cryptonight algorithm.       --scryptr

I will never buy video cards that old or that inefficient, regardless of the price. RX 5700 / RTX 2070 is the lowest I will go in efficiency. My RX 400/500 cards earned a lot of money back in the day, but it's time to move on.

It is debatable whether or not there will be a 'next big GPU coin' after ETH. If not, then the return is 20-40% per year provided you bought the cards for half of MSRP. If there is, then people who built GPU farms during the bear market for $400 per RTX 3080 will sell that RTX 3080 for $1000+, not to mention 300-600% ROI on the coins they mined at low diff and saved up. On top of that, they will make 100-300% ROI during the gold rush. So in total, that could be 5-10x your money back over 3-5 years.

That is why I'm happy to invest $100k+ in a warehouse GPU farm again when the time comes.
