Thank you for suggestion.
There are something suspicious for me or just I didn't understood the difference between Solo and Pool mining.
More than 12Hours I'm mining with 10 computers ~3 KH/sec to my Wallet and still there are no ROI

When mining to Wallet, I'll get 120 ROI only when find block and nothing else during the mining ?
When mining to Pool, I'll get 120ROI when find block and some payment for the mining ?
I'm confused . Can somebody explain please

google is your friend
https://captainaltcoin.com/what-is-pool-mining/OK I'll read it. One more stupid question:
Does I'm successfully mining to Wallet in case all clients show only
thread 0: 977 hashes, 91.94 hash/s
thread 0: 1044 hashes, 98.59 hash/s
LONGPOLL pushed new work
LONGPOLL pushed new work
thread 0: 415 hashes, 58.81 hash/s
thread 0: 986 hashes, 93.22 hash/s
There are no lines like, "accepted: 1/1 (100.00%), 72.98 hash/s (yay!!!)" , or it show such lines only when mining with Pool ?
Hi , Don't know which hodlminer you are using but it was fixed in my fork ,
https://github.com/ghobson2013/hodlminer-wolf/releasesTheTDD submitted the pull request that shows hashrate on longpoll calls.
The miners which I'm using are
Linux -
https://github.com/Optiminer/hodlminer-wolfWindows -
http://roicluster.miner-pools.com/downloads/solominers/roi-coin-hodlminer-wolf-2-cluster.rarI'm agree to use each , which work fine
I Just try with your miner on Windows hodlminer_AVX2_AES_win64.zip
When I'm mining to Wallet there I cannot see lines
accepted: 1/1 (100.00%), 72.98 hash/s (yay!!!)...
I try to compile your miner for Linux, but there are error on
