Im not going to get too much into the details between POW and POS however staking is not that easy or risk free as most people assume. If you take coins with Masternodes you first need to own a specific amount of that coin to be able to stake. For example if you choose the largest Masternode of all which is Dashcoin you will need 1000 DASH to be able to run a self hosted node.

Right now the price is $200 each, so you will need over $200,000 to be able to stake it. Sure you can stake with a smaller amount using a service however keep in mind there is a counterparty risk there because you have no idea if you can trust them or not.

Another issue is you get paid in the underlying coin such as DASH, not USD. So if the value of DASH goes down, you will end up making less money. DASH might be more stable than some of the other smaller cap masternodes out there however its still very volatile.

Pretty sure none of those ASICs come with the PSU included it is just displaying the amount of power that it uses. So you can run it off 120V if you wish however its going to be a pain because many of the 120V PSUs don't go up that high, you will need to use 2 PSUs most likely and they won't be cheap.

The way people run those ASICs is usually with a server chassis PSU running at 240V, usually it has like 10-20 PCIe connectors to power any ASIC. You can use any PSU you want but some of those ASICs will require lots and lots of PCIe connectors and PSUs for computers have a limited number of connectors. Would be best to get some 240V power hooked up somehow. Or just use the 240V from your Dryer, how often do you wash your clothes?

Only one that I know is Monero. However that is generally only profitable with the high end Ryzen processors. If you put in your CPU in google and do something like "i3-4300 monero hashrate" you might get a benchmark.

However the issue you will run into is similar with ETH, your electricity is way too expensive to make it worthwhile. I bet that mining ETH on your GPU will be more profitable than mining monero on your CPU. Go to whattomine.com and put in your info there and you will get your estimated payouts and everything. You can also go to Nicehash and they have calculators there also.

CPU mining was always difficult and very competative. Only last good CPU mineable coin was maybe BTC about 10 years ago.

Yes this is the max you can put in a closed standard computer case. I tried to get 4 or even 3 GPUs to sit in a regular case but it was almost impossible to keep the heat down. The biggest issue is that the GPU in the middle would always run hot and with the lack of space to mount fans, it was hard to remove the heat in certain areas.

Even having 2 GPUs sometimes is problematic because the GPU behind the main GPU will always run hot and you might have to turn up the fan speed on that one or underclock it more to prevent it from overheating. I have no idea how some gamers get away with doing triple SLI in a computer case. I had all those intake and exhaust fans, even at max speed it would still have poor circulation and overheat.

I discussed this before but I think the reason why more and more bitcoins are leaving exchanges is because there are hardware wallets out these days and cold storage is much easier for the average user. A few years back you had to either have a dedicated computer which was your cold storage or you had to print out those bitaddress one time use private keys which was tedious if you moved around your BTC.

Now we got many hardware wallets which are very safe and convenient to use. So as bitcoins value rises there is a threshold where people decide to withdraw rather than keep on it exchange. Last year when BTC was like $5K most people just held it on the exchange because 1 BTC wasn’t much but now how it’s almost $50K people take security more seriously. 

The reason why you see almost no volume is because almost every major exchange was down that hour pretty much. Coinbase, Gemini, KuCoin, Kraken, Bitfinex and perhaps one more that I forgot about. Its pretty bad that this still happens this day whenever we get some severe move like that. Alot of people were upset that they couldn't login to their exchange to either sell their crypto or buy more at cheaper prices. Most people could only login AFTER price has already recovered.

Hence that is why you are seeing almost no volume on that bar because the exchange had connectivity issues and didn't process any orders. Surprisingly Binance, BitMex, Bitstamp, FTX all were good during that hour. So if you used those exchanges you could of easily arb'd some profit or bought bitcoin almost at $42K which is very very strong support. Best in these condition to leave stink bids and offers. Who knows, eventually one day they might hit. And since they are in the orderbook you won't have to worry about connectivity issues.

This is not the reason why it crashed all the way down to $42K. Sure those 200BTC will be redistributed to poor people and many of them will most likely sell it to buy groceries or just sell it for cash. However it won't happen all at once. Some of them might even hold it thinking bitcoin will hit $100K eventually sometime in the future. So its not the cause for the drop.

We already knew the day it would be legal tender. I think just people, especially those on Reddit, all said they would buy $30 worth to mark the special day. Maybe it was nothing more than a buy the rumor and sell the news. However I just think the market was way overleveraged again because we had a very strong recovery from $28K and way too many people opened long positions using the futures market which is all highly leveraged.

It could be a funding reset if we are in a bull market still. Basically the same situation happened on Jan 11 and Feb 23. It had a nasty spike, funding reset, chopped around for a few weeks and made a new ATH shortly after. However the same situation happened again on April 18th and that was the peak pretty much. Because back then we werent in a bull market anymore.

So it might be a funding reset, if we are still in a bull market. However there is no way to tell. The crypto markets are still being pumped by celebrities. Not Bitcoin but mostly ETH and especially NFTs. However this all still is good for bitcoin itself. All we need right now is some Fortune500 company to say they put bitcoin on their balance sheet over the summer and we are golden.

I think that your AMD drivers got corrupted and all you need to do is just reinstall them from scratch. Seems that when the external GPU is no longer present your bios goes back to your onboard GPU. You say you got an image, what resolution is this image? I am thinking you are running Windows using a non-AMD driver.

Just reinstall and see what happens. If you reinstall and you get an instant crash then most likely your GPU is bad. Because GPUs sometimes can work with the non-AMD drivers in windows and get a display, however once you actually install the proper drivers, it usually instantely crashes indicating that the GPU is bad.

Did you do anything recently to the GPU? Switched risers? Thermal paste job? Did it overheat? Etc?

Calculating profitability is VERY difficult for ETH as to say something like BTC. BTC is easy because the fees are mostly low and BTC doesn't do any type of burning. The ETH burning is what makes its difficult to calculate how much you should be making.

If you look at,
https://etherscan.io/chart/dailyethburnt

Here you see the total ETH burnt, so when the fees goes up you should be making more however more fees get burnt. So its difficult to calculate. I actually think a couple of days ago we had a true deflationary day where we burnt more fees than total ETH rewards so the supply actually went down that day.

Can you even undervolt GPUs which are inside laptops? Been a while since I had a gaming GPU but when I wanted to do it in the past the option wasn't there. Because the GPU is not inside a PCB where you can adjust the voltages, the GPU is just added to a socket on the laptop motherboard and it has less components so the undervolting option might not be there. One reason why they don't include this option is because if they did, many gamers would probably overvolt the GPU and cause the laptop to overheat.

An external GPU which is what we all use is different, its much larger and there are more space for components, there is also a huge amount of space to put alot of copper/aluminum heatsinks to discipate the heat as fast as possible, they are also very heavy which is something laptops can't be. Hence why its not ideal to mine with a laptop, whether its a gaming laptop or not.

My advice to you is to build your house first and provide a roof under your head and your families. What is going to happen if you spend all your $20K on GPU rigs and all of a sudden the profitability drops because ETH crashes under $1000, difficulty doubles, or POS is announced in 6 months. Then you can sell the GPUS, however nobody will want to buy GPUs then because the profitability is there.

Selling GPUs to gamers is not always easy, trust me. Most gamers are not dumb and they know which GPUs were used for mining and which werent. If you make a Craiglist ad and you got like >3 GPUs for sale, they automatically assume you were mining with the GPUs. And many gamers will message and you say stuff like "I know you mined with this GPU, so I will give you $30 CASH for it, today!, nobody else will buy your mining GPUs, this is the best deal you will get and its only valid for the next 24 hours". Trust me its a headache dealing with some buyers.

I think what most people are doing is buying the equipment first and doing research after. Most people I know who asked about Crypto I told them, that you can buy the GPUs it will take maybe 6-9 months to get ROI on the GPUs and most people don't like that timeframe and they invest their money elsewhere.

I know many people who bought some GPUs, wanted to mine Bitcoin with it, and then they realized that you couldn't mine BTC with GPUs anymore. So I told them to mine ETH and they were upset that they only make like $2/day. They were expecting to make like $100,000 because after all "Crypto is a get rich quick scheme".

Like I commented earlier on another similar thread. Mining is just way too competitive right now. Your investment is going to take much longer to pay out say compared to 2017/2018. You got more issues right now with GPU mining. You got the covid which resulted in supply shortages and chip shortages. You got new high tech ETH ASICs out there that are being deployed on the ETH network everyday.

So yes, in the past. Mining always paid off. And if ETH goes to $10K or BTC to $100K then your investment will obviously pay off. However keep in mind that you are entering very  late in the game. Maybe there will be another cycle, maybe there will not. But right now its difficult getting GPUs at a decent price. And its impossible to predict ETHs difficulty in a few months or its price.

Mining right now is EXTREMELY difficult compared to late 2013 and early 2018. I remember back in late 2013 you could get a R9 280X for like $400-$450 CAD, and the GPU made around $7.50CAD a day, so your ROI was like 2 months.

Later in 2017 early 2018, it was the same story with the RX 4xx/5xx GPUs, they cost like $250 CAD and you made like $5/day/gpu with them, so your ROI was 50 days.

Now the ROI times are crazy high and I think most people are either betting on the fact that ETH goes to $10K or that their $1000 GPU will depreciate slower than their revenue. However nobody knows what top ETH will hit and who knows how much these GPUs are going to be worth when ETH goes POS sometime in the future.

Now is not the best time to start mining really.

I think it matters what type of gaming laptop. There are some gaming laptops that are heavy duty and you can game or mine all day and you won't get issues. They got big heatpipes and fans that can easily disicipate most of the heat that is created by the CPU and GPU.

There are however those tiny gaming laptops and those are not good. I think people get away with gaming with them because they game for a short while. They got small screens and not comfortable to game with them all day. So its fine for that. However if you mine with it constantely the entire laptop will be hot and eventually ill wear out all the components or swell the battery.

Like I said before, don't mine with a laptop, ever!

Bitcoin is rallying today because of the EL Salvador news which is that it becomes legal tender today. This was known for months but the President announced for some weird reason that they bought 200 BTC recently (200 BTC prior to this) and most likely will be buying more.

So given that there are 6 million people in that country and each person gets $30, thats $180M. However there is obviously not going to be every single person downloading the wallet to get the $30. And keep in mind that most likely, if someone is poor, they will sell that $30 almost immediately and cash out. So even though there is a large buyer, there is going to be tons of sellers at the same time.

I had this happen in the past and my conclusion is...

If you discover that you can mine some coin, and the profits are enormous, there is a very good chance that something is not right. I actually made this mistake in the past.

Most likely the coinwarz is providing wrong info. The algo could of changed a few times in the past for Verge. So the new algo is more hard to mine and if you use the old algo you might get an incredible speed and might make you huge profits. However after wasting a day of mining you discover its not profitable at all.

In the future use Nicehash calculator OR whattomine, they are usually more update to date and current.

You should look at the past transactions and see if the min was 55 Gwei for a few blocks. Because I've had that happen also, it would say the min fee is 55 Gwei I would send the transaction and it would never confirm even if the min fee was 55 Gwei. Then the gas fees would go up and up and it will not confirm for hours.

So look at the etherscan for the last 30-50 transactions or so and make sure the fee you want to use was included for many of them. And instead of 55 Gwei use like 57 or so. I don't know why they make it this complicated. I am guessing its so you lose the gas price and have no transaction and the miners know you will have to make another transaction with another fee OR a higher fee during congestion.

This is where I liked the BTC network better. Shouldn't get charged for failed transactions but I know they had to do it to prevent spam.

Botnets were an issue with Monero about 4-5 years ago, which led them to make a change to their algo. Botnets are almost NEVER used on Bitcoin or Litecoin because there is actually no point. The CPU of most retail computers is so slow compared to say the oldest ASIC there is no point. It wouldn't be worth the actual hassle of getting a botnet going for Litecoin or Ethereum or Bitcoin.

Litecoin has been out for a long time. There are many ASICs for it. The first one came out back in late 2013 even and who knows... maybe people are still using it to this day in some countries with cheap or free electricity. And after that there were many ASICs made by Bitmain and other manufacteurs. Even that KnCMiner TItan Cube, which is like from 2014, its inefficent in todays standards but who knows. Maybe in some countries they are still being used.
