New disclaimer when buying these 3k and 1.9k models from bitmain...
3. One major cryptocurrency which is using CryptoNight hash function is about to change their PoW algothrim, and according to their public statement, it is purposely to brick ASIC mining rigs including X3. When you buying it, you are betting that they are wrong.
loooooooooool

Not the worst bet ever anyway. Will be interesting to see which network has more hashrate after Monero forks - the original chain, or the new fork. Will the new fork really be Monero if it has little hashrate or, gasp, gets 51% attacked into can't-trust-confirmations oblivion?
Monero (among others) are planning to change the POW algo used to calculate each block, thus there can't be a 51% attack or whatever by ASICs running the obsolete POW algo. They won't find blocks and they won't earn coins, period.
This is not the same as a chain split situation where everyone is using the same algo but someone got out of sync.
POW algo change = useless ASIC
You miss the point, obviously. Some people like to say stupid and obvious things for the sake of talking I guess.
Monero's existing network isn't going anywhere, the existing chain is going to keep existing. Ofc if you keep mining you'll keep finding coins, the chain doesn't magically stop existing because some "leaders" decided to fork. If people try to call some new chain with no hashrate Monero, they are liers. Monero mining has been backed by trojaned machines for years, and many of those machines will NOT be updated to the PoW change. They'll keep mining the existing change.
Don't need ASICs to 51% attack the new chain. But let's consider if someone wanted to... the PR for the CryptonoteV7 algo change has been available for QUITE SOME TIME. Plenty of time to make an FPGA design or even tape out an ASIC if changes are minor (they are).
This is absolutely a chain split scenario. Absolutely no chance it's a clean split because so much of the network hashrate is trojaned machines or ASICs at this point.
This thread is full of noobs who can't see why these miners are an interested gamble. PoW changes don't work, monero is about to prove that.
If what you are saying is true ? Then why did Bitmain put the X3 for sale after Baikal N caused Monero Devs to announce POW change to V7 ? Bitmain has had the X3 since January according to the filing for certificate of conformity which was filed 01/23/2018. If what you are alleging is true why is Bitmain,Baikal and 2 other Miner manufacturers all of the sudden start selling Miners all at the same time ? Baikal N has also been around for months ,but not for sale to general public. Monero announces POW change to V7 and now every Crypnonight miner is on sale ? The Bitmain D3 should be a lesson learned for everyone this situation is much worse almost guaranteeing you will lose specially with the high price tag.
