So what is the reasonable time for the network to be ready for a 2MB hark fork? 1 year? 2 year? 3 years?

... it seems you all donīt get it: You canīt escape the difficulty bomb !Do your own research or cry later !  This has nothing to do with the diff bomb. This has to do with the hardware architecture of the cards. The reason it started now is because DAG size is over 2GB. In a simplified manner, you could see it as part of DAG now physically ending up on a different IC. This causes the memory controller to switch the IC it reads from more often. The larger the DAG, the bigger the part of the DAG that ends up on a different IC, the more switching it has to do. Polairs (and Tonga) both have 4 channels, with 2 GDDR5 chips per channel, making a total of 8 chips. Each chip does 32-byte burst xfers, so 2 chips provide a single 64-byte cache line. The memory layout switches channels every 256 bytes (4 cache lines). http://developer.amd.com/tools-and-sdks/opencl-zone/amd-accelerated-parallel-processing-app-sdk/opencl-optimization-guide/#50401334_pgfId-472173AMD docs say the cards use a direct-mapped cache, which means TLB thrashing can't be the problem since there is no TLB. It sounds a lot like the Pitcairn performance issues as the memory working set grows beyond 1GB (except the issue starts at 2GB with GCN3 devices). I haven't had much time for coding over the past few months, but hopefully I'll have some time over the summer to figure out what's really going on here. Could this have anything to do with the memory straps? Maybe with stock straps it doesn't slow down with every new DAG |

Think about it this way.
You are better off buying AMD RX right now even with these small hashrate drops than you are buying NVIDIA right now which doesn't have this issue.
Because by the time the hashrate drops 30%, most of us won't be mining anymore.
Its better making $6/day NOW but paying half for a GPU than making a similiar amount but paying double for the NVIDIA GPU.
Because by the time you ROI that NVIDIA we all will be making $0.25/day with our GPUs and the hashrate drop won't mean much.
But the AMD people will come out ahead since the GPU was paid for multiple times and not the NVIDIA people.
The 30% drop will happen in 20-30 EPOC, so that is just 5 months. I think ETH can still be mined then. Yes you can probably still mine ETH then but you won't be making $6/day like you are today. |

Really surprised there are so many people willing to pay $400 USD for a RX470 when you can get a GTX 1070 brand new for the same price and it gets the same speed with ETH.

So as long as you keep your Master Public Key safe there is a very low chance of someone finding your Master Private Key even if they manage to use a Quantum computer and crack 1 private key from a public key that was used in a previous transaction in the same wallet?
Yes. If someone has a quantum computer that can get private keys from public keys, then if that person gets just your Master Public Key, you're screwed anyways as they can then get your Master Private Key. Ok now I understand. Thanks for your help. |

I did not know that.
Because when I exported my private keys in Electrum there is a warning "EXPOSING A SINGLE PRIVATE KEY CAN COMPROMISE YOUR ENTIRE WALLET!"
So if 1 Private Key is exposed AND one's computer gets hacked which has only the watching address, they can get the Master Public key from there and calculate the rest of the private keys in the wallet using those 2 variables?
Yes. This only applies to non-hardened derivation, which is what most wallets use (including Electrum) as that is what allows for watching only wallets. Hardened derivation prevents this but also means that you can't have a watching-only wallet as easily (it requires going back to the offline machine to generate a bunch more addresses instead of generating from the master public key). So as long as you keep your Master Public Key safe there is a very low chance of someone finding your Master Private Key even if they manage to use a Quantum computer and crack 1 private key from a public key that was used in a previous transaction in the same wallet? |

On Reddit there is a lot of talk about public keys being easily crackable in the near future due to the advancement of Quantum computing.
Many wallets such as Electrum use Deterministic keys, so one seed can create hundreds of addresses and if you know the private key of 1 address you can easily derive the private keys of the addresses remaining in the wallet.
So lets say some individual with 1000 BTC in their wallet, never reuses the same address, each transaction change goes to a brand new change address. However since the keys are deterministic can't someone find the private key of the unspend address since they can easily follow the trail and crack the public key of a spent transaction and use that to find all the wallets BTC address and change addresses?
No, that is not how HD wallets work. The private keys are not derived in a chain one after the other. They are all derived from a master private key. It is a tree structure, not a linked list. This means that if the master private key is discovered, then all of the private keys in the wallet are known. However if only 1 child private key is known, then no other private keys can be derived. The only caveat to that is if non-hardened derivation were used and the master public key were known then the master private key can be derived and from there the rest of the child private keys. This does not require any sort of quantum computing at all either. I did not know that. Because when I exported my private keys in Electrum there is a warning "EXPOSING A SINGLE PRIVATE KEY CAN COMPROMISE YOUR ENTIRE WALLET!" So if 1 Private Key is exposed AND one's computer gets hacked which has only the watching address, they can get the Master Public key from there and calculate the rest of the private keys in the wallet using those 2 variables? |

I have R9 280x not overclocked. I started mining with claymore and Nicehash pool. Today most of the time I'm mining at 13mhs, but at unregulated time I see the mhs is raised to 25mhs in Nicehash pool. And the temperature of the card is raised to 80 degrees. At 13mhs the temp is 67 degrees. Why is that happen? Who control my card at how much mhs will mining?
What could be the reason?
My configuration bat file is:
setx GPU_FORCE_64BIT_PTR 0
setx GPU_MAX_HEAP_SIZE 100
setx GPU_USE_SYNC_OBJECTS 1
setx GPU_MAX_ALLOC_PERCENT 100
setx GPU_SINGLE_ALLOC_PERCENT 100
EthDcrMiner64.exe -epool stratum+tcp://daggerhashimoto.eu.nicehash.com:3353 -ewal mywallet.worker1 -epsw x -r 1 -esm 3 -allpools 1 -estale 0 -dpool stratum+tcp://decred.eu.nicehash.com:3354 -dwal mywallet .worker1
Mine ZEC with your 280X. Don't mine ETH. |

There are. People just choose to ignore what the experts are saying.

Of course we are seeing people switch over to Zcash, but better it be slowly like this than all at one time right?
Anyone here planning to hold onto their RX cards is fooling himself, why not get a free upgrade to 1070 while you still can? Dont be stupid.
Nobody will buy a RX 470 for $400 second hand when they can just buy a 1070 for the exact same price. |

I had the same paranoia. There are a few things you can do.
1) Print like 10 private keys, send money to 9 of them. If they all work then chances are the remaining one should work also. Bitaddress.org I think prints 7 pub+priv key pairs at a time.
2) Sign and Verify your private key. This will confirm if the private key can actually send funds from the public key.
3) Use something like Electrum with a 2nd computer. You sign the transaction on the offline computer, and broadcast on the online computer. So you can send a small amount of BTC to an address, and try to send it, if it works then just reuse that address again.
Yes I know reuseing addresses is not recommended but quantum computers are decades away.

The difficulty bomb will go away in August with the Metropolis release. However there are talks of reduced blocks rewards instead.

I am pretty sure if the OP has like 500mBTC he will launch his own Casino like already the 100's of poor cloned dice sites already out on Bitcointalk forum.
Basically it works like this. Start a site with < 1 BTC, spam on Bitcointalk and hope you get tons of gamblers which will lose everything. If you get a whale which cleans you out, just shutdown the site and start another one.
Rinse and repeat.

Basically what people fair to realize is that this is Bitcoin. The most unregulated asset out there.
Whenever some coin turns out to be a scam or some failed ICO, people are always screaming "My lawyer will contact you" and let what happens usually? Nothing.
This is one reason why the ETF was denied is because Bitcoin and Bitcoin casinos are just too unregulated.

I too experienced someone has tried to get into some of my cryptorelated accounts with my email and an old password. They too seem to have got into some accounts that I no longer use. As I used to have same password for every sites. Still the question is from where they got the passwords.
They are targeting every crypto related sites.
For your own security avoid doing that, if at some point a hacker gets hold of your password then that hacker will get access to almost all your life, that is why it is better to use different passwords for each account that you have in different websites, that way you will be able to limit the damage a hacker can do to you in case they get one of your passwords. In Addition to that try to make your password been randomized with extra special characters with capslock on some letters on it so that hackers and breachers will get a hardtime to do some dirty workds with our account and also we must set the 2fa and never used our main email interms on registering on some account that should be random to or try to make a dummy so that it adds more security to us. I would advise using a password manager, I can't stress how important it is to have a different password on each account! And how impossible it is to memorize every (strong) password for hundreds of websites. I too have used only 2-3 passwords previously, until a few months ago somehow one of my passwords was obtained, my bitcointalk account, my gmail and many exchange websites etc. have been breached. Luckily where my funds were located I was using 2FA, however, it took a week or so to recover access to my bitcointalk account etc. I was lucky the attacker wasn't very smart, I have noticed a few attempts of him trying to scam someone from my account, however I reacted with a scam accusation against myself with a newly created acc (signed PGP, addresses etc.) so no has been scammed. Using the same password on many websites (not all of which are secure), and even secure websites get hacked, and hackers obtain usernames and passwords! If you're using the same password everywhere, the same or simmilar username, you're risking everything. Use a password manager!WHich exchanges were you using the same password? I think more and more there is a good chance that there was some leak on Bitcointalk again. Because thats the common demominator in all of these failed logins that I have been getting. I remember Btc-e, I don't remember everything that was breached, because it was a lot of websites I used maybe once or twice Betcoin.ag account, gmail, bitcointalk etc. I don't use either of those services which all links to Bitcointalk again. So most likely its someone who is using the hacked database from 2 years ago and hoping someone is still re-using the same passwords. Because no other site that I am using seems to have been leaked or hacked. |

What's the guarantee that u wont run away with the deposited ETH?
That's actually the beauty of ETH compared to Bitcoin. Basically all he does is create a smart contract and everybody can go and look at the source code and find out if he is trying to cheat in some way. So anyone with basic programming skills can verify this. And its impossible to steal funds from a contract since it doesn't actually have any private keys. You just need to look at the script he is using and you can easily determine if its legit or not. |

Your experiences will not have any impact on the mathematics. Don't try to say the house edge is something it's not.
Today I tried safedice and lost it all  But I won it back here... So maybe you can use your mathematics to increase your chance of guessing the right number Congrats that you won something but it actually doesn't mean anything. You simply had bad luck when playing on Safedice and had good luck when you played on here. I highly doubt you can find some edge, you can look at the blockchain and see if there are any numbers that appear consecutively and just don't bet on those to increase your chances or bet on the numbers that haven't appeared in a while. Either way you can do the exact same statics with dice. Sure I have luck at the moment.. I just don't see why people try to convince me to stop playing here and move on to some dice site.. Never stop a winning streak  There is nothing wrong with this gambling site. The people who posted before are spreading FUD. The only thing that makes this site different from dice is that the house edge is a little higher. Right now there is no way to cheat and withhold blocks to get a certain hex number. Yes its possible but mining farms are not going to give away full blocks of 12.5BTC+Fees just to cheat on this site. And FUDsters just keep complaining saying that its very easy to cheat and the site will lose its capital and become insolvent. Its ridiculous. |

For everyone who is complaining about the USA restrictions you need to realize its not PrimeDice's decision but instead its what the regulations are calling for.
There are many websites in this forum that don't even have restrictions at all for USA customers. So where do you feel more safe? In a site that accepts regulations and prevents USA residents from gambling or a site which ignores it.
The sites which ignore these regulations they usually find loop-holes like prevent withdraws because "Someone is in the USA" or giving out "Suprise KYC/AML regulations".
Its happening more and more and more... and we all know they do it to prevent legitmate winnings from being withdrawn.
So since bitcoin is more and more mainstream, expect more of these regulations to occur.
