Thanks. I just bumped my share difficulty to 4 from 2 and found 5 invalid shares per hour. Now I decreases it again to 2.

How many shares have you contributed to the pool? Does the pool support instance payout? What is the threshold?

7 hashes is close to nothing actually. 12Mhash is very very small number. If you do pool mining, you should keep GUIminer run for a week to see the result. 

Trusting Ripple? Or wait, I don't think so. Such a company can go bankruptcy tomorrow like millions of start-ups in the world

Thanks.

Slower to submit shares can be translated to higher possibility to submit invalid shares. Is that correct?

Anyone?

The topic owner just says "If". Please be fair to him

Hi all,

I am new to BTC mining. I see some pools that say they support VarDiff (50BTC, BitMiner ...) or list VarDiff as an important feature of their pools. However, I don't understand this concept as well as mathematical background of it.

As a newbie, how can I determine what user-defined difficulty is to suit my hardware capacity.

50BTC says that if I can process less than 1000MHs I should set user-defined diff to 2. However, they say nothing about what happens if I lower it down or raise it up in in term of my hashrate, share per minutes/days or network loads, energy consumption or the similar ...

Can anyone kindly explain it?

Thanks

I thought it was vaporware 

Oh my god. I am really scared

1000+Mh/s 

Nice post. Thanks

I don't think they manage to ship those machines. If they can build such machines, they use them themselves to mine coins and sell them when mining is unprofitable

GPU master will not browse to this sub-forum  May you ask this question on hardware forum

Mining LTC bring lower profit than BTC at the moment
