Happy hashing !

 

Thanks for adding an extra kia to my name

My seller is from China 🇨🇳 and since iwantmyhomepaidwithbtc2 said he bought many used Asics in China and they are find I think I will give it a try? I am from Africa where Bitcoin and Asic miners looks like a complete nonsense because there isn't much exposure to crypto here, since you are from NY I already expect a better fixation on any problem you have with your Asic miners, lucky you.

I heard most Asic miners problem is from the power pack, I wish I can learn how to repair them myself, all I can fix are electronics since I learned the work at a young age, I know diodes, resistors and others and I also know how to use a meter to detect faults but I am sure it's going to be different with Asic miners.

EBay is a nah for me since 2012, because I had a bad experience shopping from that crime haven called Marketplace.

I don't have a faulty Asic miner yet but not bad to prepare, thanks for your replies.

Watch this video. Although in Russian, but through a translator you will understand the meaning.
The miner bought an asic m50 for $1600 and with the help of the firmware he made an asic m50s out of it, which costs about $3000

This is the only way to earn money on ASIC mining.

There's been a lot of fearmongering regarding the use of used miners since bitcoin became popular. I've seen people back then even showing vids of GPU miners blasting their old rigs with water so they can resell it as "good as new" lmao. But in my experience I've never had a problem with used miners or used GPUs, it's just about choosing which site and people to trust and buy miners to. There's a lot of trusted and proven shops here too and all you just need is to give it a little search.

If you're planning to start with mining but you don't want to bust 6000 bucks on a new rig then buying used ASIC miners is the way to go. You can also use GPUs to mine crypto but I wouldn't really advise it as some sites like newegg and the likes have imposed restrictions on how much GPUs you can buy in one go.

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.

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.

I bought a dozen of S9s in 2019 and they lasted for years without issues for the most part, but I am sure as hell if you buy them now they will start falling in no time, everyone's exerpince with used gears is different, how long have they been mining for? how did the previous owner/s treat them? it's a lot of questions, the end result is "all depends on your luck".

You can make things slightly better for yourself by not buying gears that are known to have a high failure rate like all the Antminer 17 series.


I'd stick to new gears if are available at a good price unless the ROI difference between new and used is 8 months or so, then ya, i'd take the risk with used gears, if it's just 3-4 months, I rather take less risk.

If you make up your mind and decide what gears you want to buy, you can reach out to me and I'll send you a quote, keep in mind that nearly all used gears are sold as is, you get a video showing the SN of the miner and it's hashrate, the moment it's shipped -- it's all on you, with new gears, you get a 1-year warranty.

I do have experience buying used miners and I bought it just for fun it is Zeus Hash with 1 MH Scrypt.

Short answer
Is profitable? the short answer would be no. is worth it? no, unless you mining just for a hobby and paid full electricity from your own pocket.

Long answer
is profitable? it could be if you rent your rig to https://www.miningrigrentals.com/ and sell it @ high price but the chance is slim to get picked. is it worth it? yes if you have free electricity and mine solo maybe you get luck and take home lot of money

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.

Sorry to hijack this but.

Roslyn? There is a good gear repair person here on LI and I didn't know. Yeah, I know I didn't ask.

Which, brings up the point of should we have 1 common heavily moderated post of people who do repair work and their locations.
It is entirely possible that there was a discussion about this person and I just missed it.

Why does a miner sell his mining equipment?
If you buy in China on the Alibaba marketplace, then such a purchase is risky. If this is your first experience and you do not have a trusted partner who guarantees the quality of the equipment, then it is better to buy a new ASIC. I don't know how good a price you were offered, but there are a lot of circumstances in such a case. I would not give advice until I found out the cost of new equipment and the condition and time of operation of a used ASIC.

I owned three kias. So I could be kiakiakia.

A lot depends on the seller. I live in NJ. I have a seller repair guy he lives in Roslyn NY.

I can drive to his business pick the gear up and he will repair any bad gear I have. So if you can do that

you should buy from A guy like that.

But buying from ebay is meh.

I completely agree with your message; however, can we say that Bitmain's waranties are a good plan?

They take a long time to manage your ASIC once they receive it, sometimes several months, not to mention the high fees if you're geographically far from them. The problem with Bitmain is that even if a single hasboard is broken, they'll tell you to send the whole unit back. Whereas Whatsminer, for example, will accept that you send them only the defective part, and will generally process the swap more quickly. This greatly reduces shipping costs and turnaround times, and in the case of a defective hashboard, you can continue to use your ASIC without the said board during the process time.

I think it depends on the old owner how he maintains their miner but I don't think if they will tell you that their miner is well-maintained.

If you are a newbie and planning to buy a used Miner I suggest better buy new units from Bitmain because it comes with a warranty anytime you can send the unit back to them once you experience some issue within the warranty period. Antminer 19 series have 6 to 12 months warranty.

It is safer than buying 2nd hand units that doesn't have a warranty and you don't know if the unit is well-maintained.

I looked at the problems of the ASIC you want to buy. Will you be able to check these asics or ask another miner to check them before buying?

Buying used ASICs can be a great thing, depending on the opportunities you have. To a large extent, it all depends of the ASIC model and the reseller.

I've bought all kinds of used miners and never had a single problem with them. Some have been running continuously for years, without ever having had the slightest problem.
Some models are less reliable than others, and I personally wouldn't buy some used S17s from some batches, or, for example, I'd never buy a used S9k, because even when they were new, they were complete pieces of shit ASICs.

But the model doesn't tell the whole story: I've bought 90 L3++ used (from a good reseller) and never had any problem, apart from a few PSUs that failed, but that's perfectly normal.
Another time, I bought a dozen L3++ from a random seller on Ebay (a seller located in China), and out of the 10, only 4 kept all their hashboards in a good working order. I had the first problems after 4 days of use, and this went on for 1 year.

For example, the S19pro is excellent and reliable, as are certain Whatsminers. But that doesn't mean I'll buy one of these from a random reseller : choosing your seller is very important.
The reputation of sellers is an important thing to check. Never rush out and buy the cheapest on the internet, it's better to take your time and analyze what you're buying, and who you're buying it from when it comes to used miners.

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?
