Also dev, what will you say about 150 coin reward at first 5000 blocks? If you say that it was for testing purposes, then why not made the reward 1 coin for first 5000 blocks? Testing needs high rewards? People are not as fool as you think.
That this was a 1% premine, but I burned(deleted wallets.dat) these coins, so they do not appear in the blockexplorer. To create a Yicoinnode need 15,000 coins, so 1 coin in the block is not enough.
