I had issues with ETH and low stuck unconfirmed transactions. Basically if you set a fee too low on Bitcoin, it'll stay in the mempool a few days and eventually it'll go thru once the fees go down. You can even do the RBF option and use a higher fee.

With ETH I found that is not the case. Whenever I sent a transaction with a low fee, usually within a few hours for some reason it gets REMOVED from the mempool. I noticed this because the fees would go down a few hours later, I go and check and my transaction is unconfirmed. I would have to resend that raw transaction to get it to get sent to the network.

Most likely the network is so congested that most nodes remove any unconfirmated transaction within hours and not days unlike Bitcoin. If you don't want a headache don't send any low fee transactions on ETH, just wait and broadcast the transaction then.

The GPUs found in the laptops will NEVER have any LHR type of GPUs because Nvidia knows that its not efficient to buy an entire laptop just to get the GPU out of it. Perhaps in some Dell gaming desktops they "might" add some LHR type of cards however I still doubt it. I don't think miners are going to be buying up entire laptops/desktops from computer stores just to mine with them. So these laptops and desktops are still going to be available for gamers.

The entire purpose of LHR was to limit the sale of GPUs from miners and more into the hands of the dedicated Nvidia gamers. They probably did some analysis and realised that not too many laptops are being hoarded by miners and they decided it wasn't worth the hassle of including LHR type GPUs inside actual laptops.

This LHR in my opinion is only temporarily. Once the chip shortage is over... once mining is over .... no GPUS will be LHR again. This is only to satisfy some gamers.

Well it can reach $10K however what are the chances that it will stay above that level for a long time? I can see celebrities tweeting about ETH flippening BTC and with the NFT popularity it’s a possibility. However keep in mind this coin was <$100 not too long ago. So for it to go to $10k and stay above it is 100x.

If Bitcoin did something similar from its $3000 low then it would be worth like $300,000. Which is also a possibility however I don’t see this market cap holding for the long term. Maybe some fomo along with a short squeeze. However I don’t think either of these prices would be sustainable.

My advice to you is since you only got 2 GPUs, you should just use those linux distros which are designed for mining. Unless you really need Debian to work because you want to use the computer as your work computer at the same time. However if this is just a spare rig then just install those distros instead.

I had lots of issues initially getting Ubuntu to work. First it took like a day just to install the AMD drivers. Basially kept getting a black screen for some reason. Then I had issues getting the temperature to display. Then I had issues seeing what my clock rate/memory clock was. Then I had issues with undervolting and overclocking the GPUs. Even had issues after installing the software to get it to auto mine on startup and everything. Eventually I figured it out but it took like a week. Now I can do it easily however if I went back I would just use the distros.

I googled some photos of this laptop and even though its called a "gaming" laptop I would becareful using it for mining. The only gaming laptops used for mining are perhaps those Alienware laptops which are twice the height of a regular gaming laptop. They got much better cooling and can withstand all the heat. The one you want to buy seems like it doesn't have the best heatsink and fans to disicpate the heat.

If you really still want to mine with this, my advice is at least remove the battery when mining. Because the high constant heat will cause it to eventually swell and in the rare case it might explode or leak onto you like with those old Samsung phones. Like others have said, a laptop is definately not designed for mining and a bad idea. Try and get an old RX 580 8GB GPU instead if you want to mine.

This is proof how competitive mining has gotten. Most likely those miners with 4000 ASICS is obviously some large professional farm with great deals on electric, something that is difficult for regular home miners to get.

Lite coin is not the only one. Look at ETH hashrate. Basically GPUs are sold out, if you are lucky to get one it’s most likely the slower LHR one not meant for mining, costs an arm and a leg and you would think that the difficulty would at least remain stable, however it keeps rising and rising at a high rate.

Goes to show you how much money people are putting into mining and crypto.

Congrats on releasing a miner. I think this will be very successful given your reputation. I remember using ccminer back in the good old days.

My only suggestion is that in this topic you post some SHA256SUMs or some way of verifying the legitimacy of your miner. Even though its on your github, there were issues in the past particularly with PhoenixMiner which somehow got their github hacked and a few people including Nicehash ended up downloading fake software. Posting a simple SHA256SUM for all the executable would put alot of miners mind at ease that they aren't downloading something fake.

The thing with fires is this...

I had many wires melt in the past and many GPUs go up in smoke. However as dangerious as it looks, it never lead to an actual fire. Most of the time when the wires are overloaded and start to melt, what will happen is they will no longer be able to conduct and it will just cause the system to crash. Most of the time you won't notice this until it starts to happen frequently and you need to investigate.

Same with GPUs going up in smoke. In the past what usually happened was I came home and rig was down. So I turned it back on and "BOOM" very loud noise and GPU released a big cloud of smoke, also smelled bad for an entire week. What happened was the GPU shorted out... PSU shut everything down and then I didn't know and restarted it anyways and it lead to the GPU blowing up.

The temperature that components run is important and its true that the longer you run something at a higher temp you reduce its lifespan. This is particuaruly true with most capacitors, their life is shortened because on the temperature that they are operated at. However keep in mind that this is in the span of "years" and not "months". Most likely the GPU will be obsolete by the time that the capacitors start to go bad.

A bigger issue in my opinion when it comes to longevity of components are heat cycles. If you leave it running 24/7, I think you will have a longer life span from some gamer who plays a few times a day everyday. Basically the GPUs heat up and down multiple times and that is what shortens its lifespan. If you leave it running at a higher temp constantely then its better than heat cycling it on and off all the time.

Can you even buy new RX 580 these days? Pretty sure they stopped production on those a long time ago. Maybe some old stock here and there however generally you can't buy RX580 anymore. You guys do realise the RX 5xx came out in 2017. So over 4 years ago. These are very old GPUs by todays standards.

I am sure you won't get ripped off by buying from China. However keep in mind these aren't really any decent deals. Their value will tank once mining is not profitable anymore. If you buyer a new GPU at least it'll hold it value better.

I remember selling these second hand a year or two ago and the most I could get was maybe $150 for them.

Most of the GPUs these days... if you find any in stock you can safely assume its LHR. This is one of the reasons why its been easier to get GPUs. Combined with the lower profitability the last few months or so. Things have been less hectic and been about to finally get GPUs.

The downside is that its mostly LHR. However since you bought it at Newegg you can always just return it. If you bought it from a scalper and later on found out its LHR then you are out of luck. Either way... LHR or not its still pretty profitable these days even at almost 50mh/s. Pulling in at least $5 a day or so.

So as long as the difficulty doesn't get out of control, its a decent investment. Seems like ETH might break the ATH sooner.

80% fan speed is pretty high. If you have to set it this high to prevent your rig from overheating then you are better off positioning your GPUs further apart or get a big box fan and point it at your rig. If the fans don't do decent cooling at <75% fan speed, then going any higher won't do anything except burn your fan bearing and then you will need to replace it.

My advice is get a box fan and point it in the middle of the rig, if that doesn't work then get another one and get a push/pull configuration going and you are going to get some pressure and good airflow. Make sure your window is open and you got good ventilation in your place.

No that is even a worse idea. Why?

Because for one there are hardly any CPU mineable coins out there. There is Monero however you only really make decent profit with it if you got an Ryzen processor. Most retail regular computer users only have laptops OR i3 processors not top of the line CPUs.

And even if you actually got somebody to mine, it would not be efficient mining thru a web-browser due to the limitations of the browser. It would be hashing at maybe 25% the speed. There would be no profit what-so-ever for anybody.

So I guess the rumor that we heard back a few months ago is finally true. What is the MSRP for this GPU like $3000 or so?

I think the bigger issue will be supply. How many of these GPUs will Nvidia actually make? I have a feeling they are just producing this for marketing reasons and not really to turn a profit. After R&D they are probably going to lose money on ever GPU sold.

In the end... I don't think Nvidia releasing this GPU will make the difficulty rise too much. The bigger issue miners got right now are those ASics which are being released that hash in the Gh's and are crazy efficient compared to GPUs.

Investing in futures will make you less money with the same amount of risk pretty much as buying spot. The only reason to invest in futures is if you are actively trading it. Futures at least the Perps charges you a funding fee every 8 hours, usually its 0.01%, so each month you will lose about 1% of potential profit if you go long on the futures.

You can just long the dated futures and not perps however its the same idea. They usually got a premium and will settle at the index spot price, so you are losing a little by investing in the futures.

So unless you can actively trade bitcoin every few days or so, just stick with the spot market.

I've turned them always off because I know that eventually one of them would of crashed and I would of assumed the worst and create anxiety during my trip. These days you got security cameras and everything so you can actually see your place not burned down.

However maybe if it was in the winter, I might leave it running however not in the Summer where its difficult to control the ambient temperature. Depending on the outside temp sometimes I would need to adjust fan speeds or even shut some rigs down. The weather changes drastically here and it would be too much of a hassle to leave it running without any issues.

When someone talks about futures, its usually leveraged trading. Usually much more than margin trading which is capped at maybe 10x, futures trading is up to 125x or so. And most people trade perps and not the actual futures, so the expiry date has little to do with it.

And by 50:50, I don't know what he means either.

Whether you are trading at 1x spot leverage or 5x or 10x, you will either make money or lose money with the same risk/reward. Actually with high leverage you are at a loss faster because you still pay fees on the higher leverage.

Well if you will be rich and get a lambo when BTC hits $100K it means you are pretty much rich already at bitcoin being $50K. Unless you are using crazy leverage and buying bitcoin futures hoping on 25x leverage your main position will hit $100K then its a different story. Dont buy bitcoin on leverage, a slight pullback and your investment will be gone completely. If you buy on spot you can never get liquidated.

Will it hit $100K? Who knows. A month ago people were calling for $10K bitcoin and now they are calling for $100K, so most likely neither figures will be hit. Maybe it'll go to like $99K and then go back down since everybody wants to sell at $100K.

Bitcoin won't make you rich to be honest... not anymore unless you were an early adopter. It might 2x from here and thats it. Maybe 3x but its stretching it. Look at other coins like SOL or look at NFTs. If you traded those you would be super rich.

These days it would be VERY difficult for a new pool to succeed. Most pools are very competitive and charge low rates of 0.50-1% or so. Even if your pool was 0.25% in fees your issue is you will need decent hashrate or nobody will use your pool.

If your pool has no miners then the chances of finding a block are almost impossible. So miners won't join unless there are other miners out there. The way how pools grew is when the coin was new, and there were little or no pool and miners had no choice but to join.Then the pool grew and got more and more popular.

But starting a mining pool from scratch with a fairly high hashrate coin.... forget about it.

Yeah there are a few people in my social circle that heard that I am in crypto. And every few months or so, usually during bull markets I get texts and calls about them wanting to join in and get involved.

It usually goes 1 or 2 ways.

First one is some guy who says they got like $10K and they want me to turn it into "only $100K" doing something crypto related. Like making 10x gains is something that is easily done.

Another is someone who wants to mine. They are mad that they can't use their Smartphone, Laptop or i3 desktop. They ask if they invest $1K in "crypto hardware" how long until their $1K investment becomes $100K?

Usually conversation ends in them thinking I am lying to them and keep it a secret to reap all the benefits or they discover that crypto might not be a "get rich quick" scheme.
