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?
In my opinion, I'd rather invest in new ASIC miners because they are generally considered safer since they come with warranties and support from the manufacturer. And since they're new, they're likely to be more efficient in terms of hash power and power consumption.
The only downside that I can think of is they are more expensive.
