Migração da base de dados.. Então todas as senhas foram perdidas..


ASSUSTADOR!
Opa, não é nada assustador isso já que na migração da base dados para uma nova base dados que possui regras diferentes não é como se eles soubessem sua senha, isso até dá mais um motivo para confiar na mesma.

Olha.. eu sempre quis investigar um pouco isso mas como poderia ser feito?
Pelo que percebi a Atlas te dá uma carteira bitcoin e daí ela arbitra a partir daí teoricamente?

Porque se ela passa pra outra carteira, você teria acesso, não é mesmo?

Caraca, que legal!
A walltime ofereceu essa mesma proposta para alguns usuários "testers" durante um ano. Eu fui um dos que aproveitei. Parte da taxa paga pelas ordens ativas ia para mim. Uma pena que era por tempo limitado e que não era pra todo mundo, mas achei nem interessante.
Acredito que as exchanges aqui no Brasil sejam meio olho grande devido à imensa burocracia, altos impostos sobre ls lucros e também por falta de concorrência competente (exchange fundo de quintal não conta)
Infelizmente não deve ter liquidez o suficiente para isto ser rentável.
Sem mencionar que as exchanges que permitem isso trabalham com alavancagem, o que aumenta ainda mais as fees

Tem muita desinformação aqui.
A Braziliex, tirando o limite de 150k por mês de saque que implementaram recentemente, é ótima.

Uso todo santo dia, deposito todo santo dia praticamente também, problema em meses e meses de uso só o de travar o sistema por alguns segundos (não executou a ordem por isso) e o saque de BTC demorar uns 5 minutos (para mandarem o e-mail de confirmação) para ser processado.

This is impossible.
You can reach some of us with that way of thinking (it does make sense, if we stopped buying their miners they would go bankrupt) but you're never going to touch the actual masses of miners who just want to make a quick buck.

Can't get this to work properly with RX 570 @ Adrenalin drivers, I could with Blockchain ones but it is terrible for me to have Blockchain drivers installed every time just to mine Lyra2Rev2

Wow it is obscene the amount of ASICs Monero network had.
IMHO algos should be changed every 3-6 months. That would make SURE no ASICs are being deployed.


Ethereum and other great currencies should follow Monero.

Fracasso em entender a motivação por trás da realização de arbitragem automatizada com capital alheio.


Em principio, é uma forma de alavancagem. Pelo preço que eles cobram (50% do lucro) é uma alavancagem relativamente barata. Entretanto, arbitragem não é escalável. quanto maior o volume, menor o lucro. Não sei se um sistema desse porte consegue alcançar esse limite, mas é suspeito.
Entendi. Então creio que nem mesmo seja do interesse da Atlas receber mais aporte do que vale a pena.

I have had this happen on me while I wasn't home.

I realized one card was down and told someone to go check it.

Riser was completely fried and there was an absurd burning smell but that was about it, no fire.

There are 0 reasons for algorithms not changing.

I believe most CryptoNight active dev team coins will change their algo.

Monero announced they would and so did Graft

Developers can simply change Ethash algorithm to EthashRev2 and Equihash to EquihashRev2 if they wish.
Of course I doubt this is going to happen but they sure as hell could.

ASICs are extremely fragile towards any kind of change, if they could change they wouldn't be ASICs.

What attracts most people to GPU mining is the versatility it has.
Verge is pretty mineable with ASICs and with GPUs.

It has always happened when I pushed the cards memclock too far.

Perhaps that's your issue,  you must reduce memclock or either decrease the undervolt, increase power limit.

Bios is the last thing I would check (maybe your timings could be wrong too but just think about it when everything else has been tried).

Meanwhile...

Real results, not only numbers but pictures  of RX 570 4gb. But in Europe energy isn't cheap..

https://imgur.com/a/B3moM https://imgur.com/a/APGKG  https://imgur.com/a/zYlcM
Rx 570 4 gb with kernel a1  around 700  undervolting core overvolting memory + 25W/board at the wall

"memory controller isn't full or at least seem so"

Rx 570 4 gb with kernel a2  around 800  undervolting core overvolting memory + 25W/board at the wall



Rx 570 4 gb with kernel a2  around 700  stock, etash timing + 38W/board at the wall nicknamed MegaWASP by my kid.


Back to dual mining, as its cheaper on the wall

So, if I was able to run those, how I cannot have the pleasure to see the Rx 580 up and running?




Wow these are bad results

Try downclocking memory and overclocking clocks, you'll get much better results.

Hey there, what's the results of RX 570 4GB?
I gotta change my PSU before testing this maybe.

Temp/hash/consumption?
915 kh/s at stock speed
Try 1300 and 2000~2100 memclock, might improve some %
