Ok, you say "This mechanism is currently being used with great success in the NuBits and NuShares network." Well, I'm a three months Nushare holder in your six months old Nubits/Nushares system and didn't see in all this time a single dime in dividends. All I have seen is nubits custodians losing funds in hacked/adminrunnered exchanges and Nushares holders being diluted trying to compensate the custodians lost.

Are we going to repeat the system where Blockcredits custodians will try to elevate grants to start operating in  small and untrustworthy exchanges while Shareholders are covering the losses after the unavoidables hacks/adminrunnings?

I'm sorry being so negative, but I think shareholders will find themselves pretty soon underwater as happened in nubits/nushares because, probably, it's less dangerous to exchange quickly in some big centralized sites (like shapeshift.io) than mutualizing all the inevitable losses that custodians are going to suffer in the small and untrustworthy exchanges that will agree to accept the BKC/BTC trading pair.
