Based on BSIP59,
https://github.com/bitshares/bsips/blob/master/bsip-0059.md, now 2 poll worker proposals have been created:
1.14.187 Poll - BSIP59 - Reduce MCR of bitUSD to 1.6
1.14.188 Poll - BSIP59 - Do Not Reduce MCR of bitUSD
The purpose of this change is to improve the liquidity and also the peg, at the time while bitUSD is in great shortage and premium.
The MCR of bitCNY has already been reduced from 1.75 to 1.6 and worked well up to now, it's also necessary to set MCR of bitUSD as same as bitCNY, otherwise more users would like to select to borrow bitCNY to lessen the liquidity of bitUSD。
Please vote according to your opinion.
