Given that both IBM and Intel have already stated that Silicon has reached "the end of the road" at 7-10 nm (IBM's 7nm experimental work uses a HYBRID Silicon/Germanium wafer not the pure Silicon wafers most semiconductors have been made on for the last 30 years or so), it seems VERY likely that Moore's Law is finally about to break and it's going to be quite a bit longer between generations after folks get to 7nm.

might be interesting once the fabs move to a new process entirely (hybrid or whatever, ie not silicon based any more) as that will leave the current state of the art silicon fabs with lots of exess capacity. i cant see all those old tech fabs shutting down (or converting as that would mean basically all new equipment for the new process, so new fabs may be built instead, or existing ones being expanded, leave most old tech in place as its still useful) as lots of mainstream chips will still use them for run of the mill parts that dont need the extreme speed/power savings that the new process will offer. but those run of the mill chips wont take much capacity.

some asic makers will move to the new process but they will again be competing with the big boys and their cost will be substantial, amounting to what we more or less have now.. small runs, high price, low availability.. although they will be faster and more power efficient. so not a lot will be made at 1st.

so current fabs that have 90%+ of their capacity currently used by apple/amd/samsung/arm whatever will now be able to offer large runs of custom wafers at much cheaper prices. this may let asic makers (perhaps new ones as well at the few we have now) churn out "old tech" asic chips at much lower cost and much higher volume, as right now asic makers are competing for fab capacity. at the transition to a new process apple/samsung etc will move to those, leaving old fabs with excess capacity.

this may drive the prices of asics down to the point where asic miners are much more affordable and available. power efficiency will not be much better but the absurd cost of the chips will be lower, allowing new players into the the asic party.

this would mean lots more asics on the network. difficulty would start to climb again just from the sheer numbers of new machines based on silicon, which should still be competitive if the price is right..

current farms are mainly limited by price per unit and power capacity. lower the price per unit and those who are not hugely power limited (small farms/home/hobby miners) can start to build out bigger farms. for example i have extra power capacity (125 spare amps with no upgrades) but cost of asics (mainly), plus somewhat limited availability prevents me from buying.

after all what keeps most asic miners in check besides power? price and availability. fix those and watch out.

just me guessing out loud, love to hear of any other thoughts on this.

problem is the prizes are too small since we don't get many picking for free shot at sidehack compac and 2 ltc.

thats a shame. old thread was mainly for fun even with the prize. lots of chatter etc.

hope this ones goes in that direction too.
3743  Bitcoin / Bitcoin Discussion / Re: Pain realizing early stupidity on: July 18, 2017, 02:41:51 PM
Wow so much history happened here.

In 2011, people couldn't believe that it would hit 2000k$/piece in one day; just like we can't imagine that it can reach 500k$ in the future now. (we actually can :p)

People sold their coins to buy coffees, pizzas and other crap. All lost the possibility of being a millionaire.

Long story short; You need to HODL till you make your dreams real. Otherwise It's not worth dumping. Doesn't make a bit of sense.

Why would you dump if you won't be living your dream life? Why sell your coins for a 100$ profit? or 1k$? Make it at least 500k$ and then we talk about dumping.

Those people made the same mistake and suffered for that decision. Be smart.

not sure if you were around 2011 or so but btc was very experimental (i did it for the geek/tech fun) so when it turned out you could actually buy stuff with the suddenly vastly increased value (cents to many dollars per coin) it was hard not to celebrate and do something "real world" like buy stuff. back then there was mtgox and dwolla to get btc to fiat. still new stuff at the time. after all if no one spent btc and proved it had real world value it would of most likely died. and there was no real reassurance it would last.

the stuff i bought for my wife and myself were a demonstration that the tech chain worked. that in itself was valuable. it wasnt till later when its worth and longevity were proven that i started to consider it a long term investment.

now i still buy things with btc to help with its adoption (overstock, steam) but generally replace what i sold.

HODL is the name of the game now. hoping it will help with retirement, which is edging close for the wife and i.

course if i had kept all i mined/bought and cashed out now we would be on our own private island right now. but regardless it was and is a fun ride. learned a lot and its hard to place a monetary value on that.

oh yeah played with lots killer hardware which i would not of otherwise done. bought with profits of course Smiley

i remember selling around 100 btc when the price hit $30 (whoohoo! $30!!) paid for a vacation. did the same at around $300, bought lots of toys.

ah well it was fun at the time Smiley
3745  Bitcoin / Mining speculation / Re: Can you mine at home anymore? on: July 18, 2017, 01:12:53 PM
home mining is viable but mainly as a hobby. GPU/alt mining seems to be best bet. can make a decent supplemental income (or not; make sure to do the math).

gpu miners that are properly set up are largely "set and forget." just need a place to set them up. basement/attic/garage.. some place with decent ventilation.

However I think its hard (and will be harder and harder) to catch up with the blockchain if you have an HDD. I've got an HDD 7200 rpm and was afk for three weeks. I still have 50k blocks to go after three whole days of 24h/24 syncing. It's The more people doing transactions on the blockchain, the bigger the blocks are. the same with the Bitcoin blockchain actually.

It can be better for you to sync on a SSD or to wait for sharding.

this for sure. ssds are practically a must have for blockchains. i actually run 2 in RAID 0 for eth and btc blockchains. i back them up to NAS nightly, just so i dont have to go through the pain of a complete redownload if something goes off into the weeds or ssd failure.
3748  Bitcoin / Bitcoin Discussion / Re: can bitcoin wallet be hacked by hackers? on: July 17, 2017, 01:28:17 PM
I think the best way is to create a offline wallet and put it in a pen drive. This way nobody can access it. The online wallet is too much risky, at least I can't take the risk. I just searched google and there are many cases of wallet got hacked even after high security.

USB flash drives are susceptible to bit rot/memory loss. they need to be powered every so often. do not count on one lasting years.

keep at least several thumb drives and refresh them periodically. i think just plugging them into a stand alone usb power supply (not a computer, just a charger) may do it but am not 100% sure on that. may depend on the drive.

but paper wallet and hardware wallets are best. i use use paper and a trezor myself.
3749  Bitcoin / Bitcoin Discussion / Re: Brain Wallets on: July 17, 2017, 12:15:39 PM
you could probably come up with something that may not be memorizable (so technically maybe not a brain wallet per say as you would need reference material if your memory is not perfect) but is easily reconstructed.

take you favorite author, and take sentences from each book on some order you can remember. 1st sentence in chapter one in 1st book, 2nd sentence in 2nd chapter of 2nd book, etc. maybe use chapter/sentences based on some set of number you value, math functions, dates, home addys, phone #s. perhaps reverse every other word/sentence, skip every 3rd word, whatever. can be elaborate as you like as long as you can remember the format, or write it down in a format only you can figure out as in hints.

point being you would not have to write anything down that is the actual phrase, but you would need access to the books to reconstruct it.

the numbers on this new "guess the difficulty" thread are soooo different from the old contest. lotsa double digit increases at the old thread vs the low single digit ones here.

times be changing? the asic makers just dribbling miners out this time and that limits the difficulty growth?


over 13% yikes.

3751  Alternate cryptocurrencies / Altcoin Discussion / Re: Do you think "iamnotback" really has the" Bitcoin killer"? on: July 12, 2017, 10:49:26 AM
Let's not forget he was the only person with the skill set needed to review new projects that took the time to do so so that the rest of us had any idea what we were getting into.

Board lost more with him leaving than if 99% of the rest bailed. There are a handful of people here that will push progress in this arena the rest of us are here to profit and improve our lifestyles if possible.

Sure he was up and down  and I realised he does have a slight issue in dealing with normal people.  I think it is a lack of patience and frutration that others don't automatically get things straight away that he says.

Overall very useful person lost. No point talking about it really, when and if he wants to come back I'm sure he will. YOu can ban a username and ip but not a person. If he is not back he simply does not want to be back as yet.

If anyone one person can design a bitcoin killer I would have thought he is one of the handful that could have a chance. Time will tell.

Why did he leave? Was he banned?  Is he working on a digital currency project?

Banned. He is still working on Bitnet (along with other projects, I believe). He is on steemit and github.
3752  Alternate cryptocurrencies / Mining (Altcoins) / Re: Claymore's Dual Ethereum AMD+NVIDIA GPU Miner v9.7 (Windows/Linux) on: July 11, 2017, 12:24:39 PM
Hey guys, my Eth rig recently went down and tonight I went about troubleshooting. For some reason, it was refusing to power on. Unplugged it all and went for 1x gpu. Powered on booted into Windows fine. Tried 2, works fine.

Now this is where it gets weird. As soon as I plug in another pcie cable to my power supply, the rig refuses to power on. Not just not booting into windows; completely no power. If I plug the powered riser into a 3rd gpu: no power on. A couple times while I was trying different things, it wouldn't even power on for the 2 gpus which worked a minute before. Then (seemingly randomly), it will work again for only 2x gpu.

What I've checked/done: checked all power cables/plugs on mb. Swapped power supplies with a new one.

Any ideas where I should start troubleshooting? I really thought it was my PS, but I can't believe I'd have 2 go out on me. Maybe my MB is going bad?

Rig:
Asrock H81 Pro Btc
evga 1k PSU
5x Sapphire Nitro+ 480x
shitty cpu and 4gb RAM

when that happened to me i had an msi card that was shorted at the peg socket, whenever i plugged the cards  peg connector in the psu would not turn on (shorted VRM?).

check (again) the cards peg connectors as well a the psu sockets and cables for burned/shorted connectors,  and test each card by itself with different psu peg wires/sockets. i know youve already done some of that, but never hurts to check again.

also see if the mobo is maybe flexing when the cards are in it, possibly the mobo traces are grounding?

all the psu cables are for that psu right? different psu can have different cable pinouts even when the plugs match. i accidentally mixed a season and evga psu peg cable and it would not turn on. no damage; i was lucky.

you would think that with about a 100 dollar giveaway  we would have more entries by now.. there are about 70 blocks to go and I then will close the picks.

yeah i remember your old contest, it was hard to pick a number towards the end as most everything was taken.

guess we are all so rich we dont need contests anymore Cheesy

3755  Bitcoin / Bitcoin Discussion / Re: Alts fall, Bitcoin falls ... where is the money going? on: July 10, 2017, 08:09:35 PM
You thought that positive growth will be permanent?

No but when Altcoins dump they are usually sold.

And they can only sell for Bitcoins which should then rise

Which are most likely then sold for fiat.

i may unload some btc for usd/eth/ltc, but not a lot.  i also have some cash reserved for picking up on any good dips however it goes.

figure if btc  splits ill see whats up at that point.

3759  Alternate cryptocurrencies / Mining (Altcoins) / Re: Claymore's Dual Ethereum AMD+NVIDIA GPU Miner v9.6 (Windows/Linux) on: July 04, 2017, 10:13:03 PM
Why don't this miner use the full GPU clock available?
I have a R9 390 with 1050 Mhz GPU clock and when running the Claymore miner in dualmining mode iht just uses 1000 Mhz roughly ..
When averclocking to 1100 Mhz it still uses just 1020 Mhz. Why is this so and what can I do to eliminate this problem?

Thanks in advance! Smiley

might be hitting a power limit.

undervolt it and make sure power limit is high enough.

Anyway, don't believe AMD care about hashdrop at all, even less that they work with claymore for resolving this.

now that amd has miner edition cards i think they would want to fix this. otherwise they are handing nvidia customers as nvida has ming cards also.
