There are only 20m mined coins, no matter who owns them. And 50m is premine. Now if you discontinue mining, 71% will be premine, instead of the promised figure of 5%. Thats 14x more premine than you originally claimed.
Yes, more coins will be generated through POS, but this is proportional to the coins held, hence, if mining is discontinued the 71% premine will be unchangeable. It will never be 5% premine as you initially claimed.
You own the exchanges, 71% of the coins. And you figured you want to freeze it here.
If leocoin is as transparent as you claim, please allow it to be traded on the major independent exchanges.
I see no reason why other exchanges could not trade or start trading LEOcoin. The LEOxChange was started to create liquidity so that owners of LEOcoin could buy and sell if they wanted to.
