PCI for the sound card, LAN card, and old GPU. There's actually a converter PCI to PCIe but transfer speed doesn't faster than PCIe. usually GPUs to mining using PCIex1 and PCIex16.

Yes, purchase M2 to PCIe adapter.

different at from boost clock, temperature system, and noise system, heatsink size, and amount of fan. I suggest getting 8GB for keeping long periods to mining.if you mining in Ethash Algorithm, it considering your size memory.

for type VRAM, some miners very happy if they get a Samsung doesn't mean other types of VRAM is bad but has a bit difference amount hashrate. you will know VRAM type after buy.

if the hacker was hijack a server. someone or admin that server can saw something wrong on the server. such a server working very slow unusual. the sound of the fan sounded unusual. same if hacker hijack a smartphone, that's more unusual. a batteries drain faster, mobile phone faster the heat and slow.

If mining the altcoin using a server still profitable, such ETN coin but if server using to bitcoin mining, I think don't profit because of Global hashrate and network diff to high. although using Mobile phone or browser. (but that fact don't influence hacker because he/she nothing to lose because a server, mobile phone not his)

What the say your friend is true.
You can read how much Network Difficulty Bitcoin. And your hashrate very bit. Something quite impossible mining using browser, let alone Bitcoin. You must compete with ASIC miners.

What the series your GPUs?
- if AMD series can try reset CMOS if GPUs doens't Mod Bios.
- if Mod bios , patch using Atikmdag.
- or can lack power. You can calculate all how much power consumption would need.

I assumed he/she true total noob and doesn't know search function or maybe has been searched an article but he/she don't understand but I understand all need the process.

OP being drunk, please another member don't trust.
Are you never read about Network difficulty, Dag Size and Hashrate. And the pool must be verified (Red Flag) don't follow the instruction for register, this' probably scam.

No, trust me dude,
You can compare with Hashrate GPUs such RX480 4GB on mining (example on algorithm Equihash or Ethash). Your Hashrate determine your profit.

Fees of the Pool, Hashrate on the Pool, Legit of the Pool, Stable of the Pool, Frequency find the Block, and easy if withdraw.

It's the normal situations if ETH POS but I doubt for ETH POS if looking history ETH. Although ETH POS, only switch another coin many unexplored coins.

Almost some miners mining these coins because a profitable coin considering the GPUs series their have. Such an AMD series excellent on ETH, ETC and the NVIDIA series excellent on ZEC although high diff.
If you want another coin, you must go to whattomine.that's corresponding how many your GPUs.

do you use mobile phones?

oh no..
your device will overheat and your device gets stuck. the battery drain faster. Of course, you have a little hashrate. Your profits aren't enough to fix your device if it breaks.

Come on dude,
The phone is only used for calls, messages, stereaming videos, open social media isn't used for mining.

Profit a coin depends on pool hashrate, network diff, and coin price when convert to Bitcoin/USD but you can try Equihash algorithm such Zcash coin.

Probably due to network security, low coin turover, low coin prices so rarely traders who sell or transfer so little income from traders fees. Exactly the reason doesn't know why.

oh .. what will happen with my GPUs, maybe the GPUs will be idle or be the toy that is on the wall and the sellers will be a bit disappointed because they have stock his gpu in large quantity also they will be short of profits and gamers a little happy because the price of GPUs will be normal again. But good is the rumours. we'll see what happens if Bitmain releases.

You should see whattomine, how much hashrate 12x1050 and 6x1060. and compare how the average price difference is both. and the price of coins fluctuates when converted to Bitcoin.

When mining using Nicehash, it switches an algorithm which is considered a profitable. Then the coin from algorithm it on convert to Bitcoin while price a Bitcoin is decreasing. That's one the cause to be your profit has low.

yes, I hope like that.
besides the miners who were let down by GPU prices, also the gamers were very disappointed. Usually their (gamers) buying GPU very easy and with the normal price but now very difficult and with expensive price and solar panel environmentally friendly electricity.

if for  Beginner in mining like me. I have a bit question:

Windows10 support, a monitoring, Overclocking, profiling, RGB color very easy, is it in Linux as easy as in windows?.

when the new miners want to build a Rig. their start reading and watch the tutorial such about how to build the Rig, How to do solve the problem on their Rig.there are tons and tons of tutorials on YouTube and forums on. whether in youtube/forum about the tutorials concerned with mining as much as the tutorial on mining using windows10?.

Sounds good, would using a solar panel for your electricity but, surely the cost is very large for equipment and installation when compared with ordinary electricity. Yes, the problem for new miner is when to buy a GPU and price GPUs increased 100% and empty stock.
