I consider carefully all about monero. I suppose unfair distribution happens due the super-optimized miner probably
There's nothing unfair going on that I can see. If you got in early when the difficulty was lower, you could have mined a higher percentage of blocks, but the block times have been pretty consistent from the start AFAIK. Of course, no one has a block explorer for MRO, but you can read out the time stamps in the daemon. There are some fast blocks for the first few, then some longer blocks as things slow down and difficulty adjusts. Oddly, I do see a few instances where the timestamp on the next block is earlier than the timestamp on the previous block (e.g. block 100 is 1397822726, block 101 is 1397822717), but perhaps the time stamp comes from the PC that finds the block, so you could easily have a skew of several minutes given that PC clocks are notoriously prone to being off by several minutes.
At present, we are on block 32442, and with an average payout of 17.3 MRO per block we have mined roughly 560K MRO out of the target 18.4 million. So considering MRO was launched on April 18, in about the first three weeks we have mined 3% of the total MRO. Considering many coins have had 1-3% premines, 3% distributed among the miners that came on board in the first three weeks is peanuts.
