+ | < ArtForz> I kept about 15% | ||
+ | < ArtForz> ~40kBTC currently | ||
+ | < ArtForz> I'll probably keep on selling 80% of daily production or so | ||

+ | < ArtForz> once a mienr (or a bucnh of collaborating miners) get > 50%, they can claim all generation and block transactions from getting into the chain | ||
+ | < molecular> | ||
+ | < molecular> | ||
+ | < ArtForz> I prefer to add hashrate slowly to stay at 15-25% of total network | ||
+ | < ArtForz> it simply doesnt make much economic sense to grow beyond 33% or so | ||
+ | < ArtForz> you're effectively competing against yourself | ||
+ | < davex__> artforz: why does that matter? | ||
+ | < ArtForz> except you dont | ||
+ | < ArtForz> lets say rest of network is 100Gh/s, you add 10, you're 9.1% of total, you add 50, you're 33.3% of total | ||
+ | < newsham> what artforz is not counting on is that once he has large monopoly, he will be able to extract nice transaction fees if he so desires :) | ||
+ | < ArtForz> so ~ 3.5x payout for 5x the hardware | ||
+ | < davex__> artforz: yeah true... | ||
+ | < ArtForz> yep | ||
+ | < ArtForz> and a mining cartel is really really obvious | ||
+ | < davex__> because you get lots of simultaneous solutions submitted? | ||
+ | < ArtForz> that and nobody else suddenly gets blocks | ||

+ | ArtForz> nah | ||
+ | ArtForz> I run 4*5970 on 10.12 no problem | ||
+ | ArtForz> seems to be even a bit faster than 10.10 | ||
+ | ArtForz> btw, the multiGPU slowdown and CPU hogging is limited to OpenCL in sdk 2.2/2.3, CAL works fine | ||
