1  Alternate cryptocurrencies / Speculation (Altcoins) / Re: will tether collapse? on: October 19, 2018, 06:39:31 PM
I would not want to be a pessimist, but I think that Tether can make some unpleasant surprise in the future for the entire cryptographic market
Do you think that UDSC, PAX or TUSD more stable and valuable USDT? I wait when we will live without this streak USD worldwide. This is a main idea of cryptocurrency. Not for USD profit. But I have more and more doubt that it will happen

I heard the those coins (stable) have federal insurance. So they are more reliable.

It really depends if that is a shtcoin, Some crypto  is for profit purpose only which means to attact the community to invest on that project if though they are not doing anything just creating a "Joke" whitepaper.

What do you think of Bitcoin Cash?

Ok I'm ready to burn my computer.  Someone please help me.  I have a R280X that runs Cryptonite at 485h/s and according to the charts should run Equihash around 290 h/s.  I'm running claymore 12.6 on Slushpool and when the miner starts it does 275h/s.  It then begins to throttle down in steps down to 145 h/s and sometimes lower.  I recently watch it go as low as 40 h/s before climbing back up to 145 h/s.
Does anybody know why the rates are so low, and also the -i and -il commands do nothing to the hashrate.
I'm running the "blockchain" drivers but had the same problem when running AMD 15.2.
Any ideas?
Bob

Need afterburner and set the fan speed to 64% with -25% power. At least on my 290x's. Otherwise it throttles on stock fan speeds/curves. Also slushpool is losing you money unless you dont pay for electricity, even then altcoins will bring more profit, ethereum is easy to trade for bitcoin.

I have R9 290. I run them at lower voltage and frequency so that they are profitable.

Today i released a little hack that completely removes dev fees...

Do you have the source code?
5  Alternate cryptocurrencies / Speculation (Altcoins) / Re: Is Electroneum bigger and better than Bitcoin? on: November 04, 2017, 04:02:06 PM
Bitcoin is the first coin in cryptocurrency. It has created trust from investors through the price increases. I don't believe any coin can replace Bitcoin.
Electroneum is not comparable to bitcoin, bitcoin is the best amongts all cryptocurrency. I dont think electroneum will be a having a huge price in the future. Bitcoin is gaining popularity ever since and until today.

Even if the Electroneum can beat Bitcoin Cash, it is a good achievement.
6  Alternate cryptocurrencies / Speculation (Altcoins) / Re: All altcoins dumping at the moment. on: September 22, 2017, 02:53:54 PM
There are other reasons why there are downtrend on crypto price for example Mr. Dimon warned that governments will eventually crack down on cryptocurrencies and will attempt to control it by threatening anyone who buys or sells bitcoin with imprisonment, which would force digital currencies into becoming a black market. These are the latest comments from Dimon attacking bitcoin. Earlier this month he called the cryptocurrency a "fraud". His comments, along with several prominent hedge fund investors, came before a sharp sell-off in bitcoin. The price for one bitcoin fell from around $4,340 to as low as $2,981.05 in the days after his comments.

I think Jamie Dimon will be punished by manipulating the coin market.

The message "GPU #x returned wrong data" is mostly due to bad ram overclock or very high core clock?



Yes. Just reduce the frequency.

ram or core frequency?


That is try and error. Mostly RAM.

I see some of you guys getting 300+ H/s from RX 480's.
What is being done doing to achieve that?

Modded memory timing.

And soon it will be ready?

I think it will be ready in a week also.

Then why do not you do a miner ?

There hasn't been enough incentive to do it.  If someone offered a large enough payment, I could write a Linux ZEC miner that is at least 10% faster than Claymore 9.2, and probably have it finished in under 30 days.


You can add a 2% devfee just like Claymore does and make much more than 10BTC.

That's a possibility, but by no means a certainty.  ZEC could drop to $10.  The majority of ZEC could end up being minded by botnets, or by big farms running private miners.

I've been approached by a number of people asking me to write a private (and possibly public) miner, so it won't be long before I get the right incentive to write it.


Can you miner be faster than the  private miners?

Put 0% Zcash for free.

This is now just profiteering.


It is making a profit, I agree. But I did a lot of work to make these mods, I believe my work deserves it's worth in time. If you want it for free, you're just as much a "profiteer". I mean, you're welcome to use Claymore's original and pay 2%.

Even with 0%, it is not profitable.

You need to swap the memory slot or change a new memory. I had this problem before, and solved it by doing that.
13  Other / Archival / Re: What would you say to people who advice you to sell all your bitcoin? on: November 20, 2016, 05:17:10 PM
I will simply listen to them if i need money, and if i don't then there will be a straight "no", as i never sell my bitcoins if i don't need any money, i like keeping them as i believe bitcoin will get more progress in coming time.

That is right. When we need the money to buy things, we can either sell the bitcoin for fiat or use bitcoin directly.

Why aren't you joining the open source miner contest?

I did.

That is good. More information.

Crowdfund for open-sourcing tromp’s solvers / funding Cuckoo Cycle

https://forum.z.cash/t/crowdfund-for-open-sourcing-tromps-solvers-funding-cuckoo-cycle/2465

"I'm happy to open source my solvers in exchange for a 20% community contribution to the Cuckoo Cycle Bounty Fund, which will offer up to 100 BTC in bounties for disproving my claims of the Cuckoo Cycle proof-of-work being optimization free. See

https://github.com/tromp/cuckoo137

for details on the existing bounties. The remaining 80BTC, if claimed, will be at my personal expense. The fund allows for significantly raising the reward for a performance doubling from the current $500 to a much more enticing 10BTC, and will scale with the 2-logarithm of the actual improvement, so that a 1024x speedup (or memory reduction) can claim the maximum 10*10BTC payout.

The bounties would be guaranteed for at least 4 years, plenty of time to encourage some serious attacks on Cuckoo Cycle.

While you're all no doubt keen on supporting advances in crypto-currency research, you may also be curious to see some well optimized Equihash solvers, to which end I offer the following in return.

On a 4Ghz Intel Core i7, one of my CPU solvers reaches 2 Sol/s single-threaded, 4.3 Sol/s 4-threaded, and 6.7 Sol/s 8-threaded, while another solver reaches 5.14 Sol/GBs single threaded for peak memory.

On an Nvidia GTX980, my CUDA solver reaches 17.6 Sol/s.

Open sourcing these solvers will take place if donations reach 20 BTC by noon Oct 14 (with a possible one day extension if the goal looks within reach at that time). If the goal is not met then donations will be returned (unless you're happy to unconditionally support Cuckoo Cycle bounties).

There are multiple ways to make donations. The escrow options are detailed in cryptogoth's companion post at

Crowdfund contract for open sourcing GPU miners
Later tonight, I'll be uploading a contract to Ethereum mainnet to raise 20 BTC for open sourcing John Tromp's GPU miner, with a deadline of 14 October 2016 (in less than four days) at 12noon EDT (16:00 UTC). I'll do a test run through several accounts I own and any volunteers who happen to be awake, then I'll post the annotated transcript from the blockchain to explain how the contract works. The contract will accept contributions in ETH, and OgNasty will accept contributions in BTC. Both w…

The prize is $10000 for each miner and it has to be open source. Good luck getting Claymore involved... Grin

That amount of $10,000 is too low for Claymore. I believe that he earned hundreds of thousands from his miners.
