How long does your used asic miner lasted for? If you are using used mining equipment please drop your results on here, have you ever bought a particular used equipment that lasted for years with no problems at all? For how long actually?
Could you advise someone to buy used Asic miners too? Or newer is safer? Does new or used matter?
Do new asic miner have problems in the short term too?
if you use a product from Bitmain it will last a very long time, because used miners from Bitmain are very good and last very great material.
I bought in 2018, so far it's still running well.
Not all Bitmain asics work for a long time without problems, but many S9s still work fine, but they are practically not used because they are not profitable. S19 is also a good series from Bitmain, but you need to look at the difference between the price of new equipment and used.
