[Committee Proposal]Reduce market fee reward ratio for bitCNY, bitUSD and bitEUR

[bitcrab]

Three committee proposals are created to update bitCNY, bitUSD and bitEUR.

1.10.53309 set bitCNY reward percent to 60%.

1.10.53311 set bitUSD reward percent to 60%.

1.10.53312 set bitEUR reward percent to 60%.

All the three proposals will expire at 2019-12-10 00:00:00 UTC.

Currently all the above 3 smartcoins are set market fee as 0.1% and reward percent as 80%, the proposal for this change is based on below considerations:

1. BTS need more income to buy back BTS and support the DEX economy, now bitCNY income is much lower than months ago,  this change can double the market fee income of relevant smartcoins(means the part that go to system will change from 0.1%*20% to 0.1%*40%)

2. market fee actually paid by LTM change from 0.02% to 0.04%, it is still very low.

3.60% sharing to referrer is still a very high incentive.

Committee members, please check and vote according to your opinion.
