Will it affect the hashrate if the PCIE slot is running gen 3 or 4? I mean if i were to google hashrate for certain GPU, i will find various number some high and some low, even when they're sharing the same settings. of coz they didnt mention their rig specs. One thing for sure if i were to use eGPU via thunderbolt, the hashrate definitely lower than direct PCIE connection on a  PC even with the similar recommended OC, PL, MC, CC, with those who got it high hashrate.

Its good news ?

bad news for miners not necessarily good news for frequent users. it only eliminate the mismatched of gas fees due to volatile congestion. in the end fast transactions will still cost you more gas. and it will be burned instead of giving it to miners.
not a win win solution, more towards to stop some miner uses bot to increase their profit and congest the network. since it will be burned, and no point doing it and hopefully the gas fees will be less volatile.

so in the end they still need to sort the issue of limited transaction per second only fess be cheap, transitioning to PoS can be a way but it brings us back to how government runs monetary.
Btc has limited supply but eth doesnt.

do we need to do anything if holding ETH?

Yes, based on today prices 5usd/day. a month ago i was at 3.xx usd +-
If get more just make sure to turn on ac 24/7, you know its just a cost of another GPU, 1hp ac of 11,500btu can cool 30 cards remain ambient temperature of 38C in the afternoon and 31C in the night.
and yes i got switch on a water fan cooler for 8 hrs during afternoon to help cooling since humidity maintains about 30 to 37%, auto switches off once the humidity raises above 40%

It seems hardware distributors are reading this thread, prices all jack up as per 1 month ago, when everyone thought lhr unit cannot mine profitably.

Check your settings again, it would seems like they dont recognize you.
Slush, nicehash, poolin, hiveos, antpool, pick any that you have control over with or you are familiar with the payout. For me not much difference between pools.
Possible, one gpu / 2 gpu rig, if you already have existing mobo, 7k can buy 3 more gpu.
provided you can find the gpu you want. now no stock again. you still make the same with eip1559, so miners continue to build rig + current chipshortage situation.
I heard they place less order on July due to fear, because a lot of FUD of mining crashing, eip1559 etc. therefore a window of cheap gpu available in early July, market has no stock even you got money to buy.
allocation also not like you order bulk can get your stock, scalper cannot give you 8/ 6 gpu of the same variant. people who hope to buy at msrp will rant more, but they can actually buy scalper and miner back to msrp or roi when not using...
Asic manufacturers are banking POS will be delayed again, hoping to sell their ethash machines. scrypt all sold out, ethash able to score on high risk. i dont see the logic if i cannot continue to make another 100% gain.
Btw, continue to build rigs to pass time since shops are not opening anytime soon and dine in also.

I'm using HiveOS to mining ETH, is this kind of temperature is normal for the RTX3080Ti? (3 x Ventus 3x and 1 Gaming X Trio).

anything in particular you found out ?
its the same with monero mining, just so called slightly better returns due to lower difficulties for now. in the end of the day you will still want at least 30 to 40 rigs running it.
its never too late to join, just dont have high expectation like its a quick money scheme. treat it like renting out property instead.
am still building rigs every month. as long as there are still pow blockchains, you will have passive income. have a good mix of cpu,gpu, asics.
maintaining balance sheet is important.

from what I see, eth2.0 still got long way to go, at least another 6 to 10 months time if they managed to solve their current issues in time.

even after that, still got plenty of other profitable coins to mine

lots of news outlets are still kinda shallow on crpyto mining, giving gamers big hope that eth2.0 will end the GPU draught

3060 TI LHR at 60mh/s
3060 LHR at 50mh/s

Nice info. Note Gminer already increased the fee to 1%

Answer from Nicehash


BTW ETC already a fork for ETH

Another news ETH DAG size will be 5GB starting tommorow, some Asics maybe no longer able to mine ETH
