Pre hracov len dobra sprava...

[brambora81]

to bych nerek to nma vykon tak proc by to hraci kupovali

[racecar]

Ziadne extremne predaje od minerov, ziadne extremne predaje od hracov.

V kazdom pripade ziadne predaje = ziadne peniaze AMD. Co teda asi nieje dobra sprava.

O cem mluvite? Jake zadne prodeje? Pri cene 4200$ za BTC se prodá vsechno vc vegy. V cine je energie levna, tohle se bude vyplacet jiz navzdy, již i nekteri analytici z Wall Street mluvi o cene 50 000

Bitcoin se netezi na GPU ale na specialnich asic kartach.Na GPU se tezej jen ostatni meny jako ethereum coz se na vega rozhodne nevyplati.Je to asi nejhorsi karta na mining na trhu momentalne.

[PET5]

Jenže první, co těžař s právě získaným ETH udělá, že jej vymění za BTC. Proto se ta těžba na grafikách stále vyplácí.

[HEAD]

Jenze cena ETH zatim nestoupa, ale obtiznost je prej neuveritelna.Takze na jeden bitcoin musis natezit desitky ETH coz ti bude trvat nekolik mesicu

btw konec ETH miningu se blizi.Budou tam velky zmeny, ktery to prakticky zabijou pro tezbu GPU v pristich mesicich.

Však také na burzách se obchoduje nejčastěji se zlomky bitcoinů. Prostě vytěžím zlomek ETH a ten co nejdříve vyměním za ještě menší zlomek BTC. Pak už jen pozoruji, tak ten BTC hezky roste. Jednou za den mohu vyměnit BTC za USD a zpět, a pokud mám dobrý odhad, tak si o nějaké procento ve výsledné sumě polepším. Nebo pokud nemám čas, nebo odvahu, tak BTC budu držet delší dobu a za USD jej vyměním až se výrazněji zhodnotí. Nebo to všechno nakonec krachne a budu v pr...

Nasel by se tu nekdo, kdo zasveti uplneho neznaboha v tezbe kryptomen? Idelane treba prez skype chvili o tom pokecat. Otazek mam dost, tak nekdo zainteresovany by se mi hodil.

S tímhle souhlasím... Vega je na tom s účinností relativně špatně, ale nějaký ten výkon tam je a pokud to bude jediná rozumně dostupná karta, bude se prodávat i na těžbu. Např. i u nás se najdou těžaři, co mají dokonce svou vlastní menší elektrárnu, se kterou ty těžařské farmy napájí a ty to, pokud nebudou mít problém s chlazením, tolik trápit nebude.

A co s tou vegou chces jako tezit?Ethereum prochazi zmenou, ktera znici GPU mining
Zeptej se kohokoliv kdo tezi Ethereum a odpovi ti stejne.Obtiznost je tam tak silena, ze je temer nemozne se dostat na ROI a bude jeste daleko hur.
Momentalne tam probiha tzv obtiznostni bomba, ktera umele zvysuje obtiznost o desitky % kazdych par tydnu.

Btw 1bitcoin je 15ETH coz odpovida i +- dolarove cene 15x300=4500USD.Takze to neni o nic vyhodnejsi nez to prodavat na dolary.

No co, to by mela byt konecne lepsi zprava a teoreticke snizeni cen treba v novem roce.

Takže se dá říct, že Vega je na tom s energetickou účinností stejně jako GTX 1070. Takže pro těžaře nebude tak zajímavá, jako Polaris 570/580, ale v případě jejich nedostatku se na těžbu používat bude, tedy pokud ta mánie díky nějakému zákroku neskončí.

Vyměňovat ETH za USD je v současné době nevýhodné. BTC stále roste a úspory v BTC se dále hodnotí. Vydělat (prodělat) se dá také spekulací BTC/USD.

preco asi? Lebo sa rapidne zvysuje pocet minerov ... narocnost rastie ked sa zvysuje vypoctovy vykon cloudoveho systemu

Je to umele hnany nahoru aby se pripravili na POW.Ten nakonec prijde az na konci 2018, ale mezitim to nastavej tak, aby se na tom nedalo vydelavat GPU miningem.
ETH je proste mrtvy na tezbu v dalsich par mesicich.

HEADe, o tejto informacii z tvojej vesteckej gule si porozpravame, az sa to naozaj realne prejavi na trhu (dostupnost produktov a normalne ceny).

asi tu nikdo neumi cist.Sami tvurci etherea to tvrdej

For the Ethereum Homestead release in March 2016, code was added to create a difficulty bomb on the Ethereum network, often referred to as 'The Ice Age'. The purpose of this code was to increase the difficulty of Ethereum mining over time as it came to the end of POW and into POS with the difficulty increasing exponentially as we got closer to the expected POS implementation. The original planned date at that time for POS was the end of 2016 but when they realised this was not feasible, the bomb was delayed and given a more gradual initial impact.



We are now coming towards the end of 2017 and as Casper has been delayed, we are in a situation were mining difficulty is increasing exponentially. To combat this, the devs are discussing another delay of the difficulty bomb, pushing it out by approx 16-17 months and giving themselves that time to finalise and implement Casper. After todays call, the current expectation is that this update will role out as part of the Metropolis Byzantium update which they are expecting to go live somewhere around the last week of September or first week of October depending on testing.

So what does this mean for us Miners?



I’m sure everyone here has been aware of the massive difficulty jumps we have seen while mining ETH over the last number of weeks / months. We have had 2 very significant spikes in the last month or so with the first coming around July 10th and the next coming around July 31st. Both of these spikes where caused by difficulty bombs with the next one expected to land on August 25th, the following one on September 24th and another on October 31st.



For those of you wondering what the real world impact of these bombs going off is, they are significantly increasing the amount of time it takes to mine blocks. Before one of the first bombs went off in mid May, it took on average about 14.5 secs to mine one block which contained 5 ETH. If you look at this chart https://etherscan.io/chart/blocktime you can see the exact times each subsequent bomb has gone off to the point we are at now were it is taking about 21 secs to mine 1 block of ETH. With the current implementation of Ice Age, this is what block times will look like over the coming bomb drops:



August 25th - 25 seconds
September 24th - 32 seconds
October 31st - 41 seconds



As you can see, the block times are increasing exponentially and by October 31st, it would take 41 secs to mine 1 block of 5 ETH, meaning we would earn approx half of what we do today. (Not taking into consideration any new miners coming on board which also drives difficulty up).

+

After the dev call today, we now know that the update to delay the bomb into 2018 will not happen until after the bomb drop on September 24th meaning there is going to be a very tight squeeze on miners over the coming weeks, possibly to the point of it costing more in electricity for some people than what they earn. To make it easy for you to calculate, whatever you earn today, it will be about 19% less after August 25th. Whatever you earn then, it will be about 28% less after September 24th. Again, none of this takes into consideration rising difficulty from potential new miners coming into the network.



When Metropolis Byzantium does go live, we will see the network return to approx 15sec block times however the issuance will likely reduce to 3. This means that we will essentially earn the same amount of ETH then as we will between Aug 25th and Sept 24th (3 per 15s is the same as 5 per 25s). With this happening, the only thing that will drive the difficulty of mining will be mining hash power so I would like to touch on that for a moment. Below is an overview of the mining hash increases we have seen in recent months:



1st May to 1st of June the total network mining hashing power grew from 22.85TH to 34.41 or 50.6%.
1st June to 1st of July it grew to 59.19TH or 72%.
1st July to 1st August it grew to 78.26TH or 32.2%.

However, from Aug 1st to Aug 11th, it has only grew to 79.86TH which is approx 2%. This massive drop off in mining hash power growth is directly related to the difficulty bumps we are seeing in the network. I expect that after the bomb on August 26th, we will see a significant number of miners leave the Ethereum network and move to other alt coins, massively impacting the profitability and difficulty of those coins as they go. I believe this will actually cause a regression in the Ethereum mining hash power through to the Metropolis Byzantium update. After this update, I expect our mining rewards will be equal to what we get after the August 26th which is going to be approx 20% less than what we get today. If that is going to be an issue for you, you may want to consider selling your rigs now or start researching what other coins you can mine to stay profitable.



In summary, it is going to be a very volatile few weeks for mining. After the difficulty increase on August 26th I expect we will see a large number of ETH miners move to other coins which will have a large impact both on those coin networks and coin prices. ETH rewards will be approx 20% less than what they are today and approx 50% from September 24th until whenever Metropolis Byzantium launches
