You might be more familiar with crypto than I am. Plus I often hope for the best. But I agree that i can’t be bad to be prepared for the worst 
If Nu is successful, NSR holders will have a good time.
If B&C is successful, BKS holders will have a good time.
So from a pure monetary perspective each NSR holder (based on design at snapshot rime, although I like the distribution model proposed by you! will become BKS holder.
As almost all initial BKS holders are NSR holders, one might say, there’s not much to lose for NSR holders, if at least one of the two prospers (and if the BKS holders hold ).
I was hesitant and almost refraining from writing the following, because it sounds super pessimistic and partly offensive.
But maybe it’s necessary to voice this kind of thoughts…
When Nu was funded (not the initial sponsor but the point when the NSR have been sold) PPC and BTC have been at rates far above the current rates.
People who received NSR in exchange for PPC or BTC are (monetarily) far better off than with the PPC and BTC if they had kept them.
But this is only theoretically true.
The market for NSR is thin. It’s impossible to sell large amounts of NSR without plummeting the price. So while the market cap of Nu is impressive, NSR holders can’t make much of it (currently).
You can wait for NSR markets to become more liquid, or you search for other ways to turn your shares into fiat (as this is still required to pay bills…).
Creating a distributed exchange (there’s for sure demand for it) and giving the shares to NSR holders increases the chances to make either one or the other to money if necessary.
Money moved from PPC and BTC to NSR. Now it might move from NSR to BKS.
Peercoin is still here and doing well (e.g. Emeth’s PeerApps will be supported in the next Peercoin release).
Peershares are doing well and have been forked by the Blackcoin community.
Nu is still here. The peg could be defended even in recent dark times.
B&C might come to offer a decentralized exchange.
Whatever will come after that - all that has been created so far is helpful, useful, necessary, in one way or another if we want to get an alternative, maybe even a replacement for the currently dominant monetary system.
It did begin with Bitcoin, but it didn’t stop with Bitcoin.
Nu might need to take the next steps.
…if only I knew which are the right ones…
I tend to believe in the abilities and the visions of those major personalities.
Don’t take this for blind belief - I try to question what is proposed.
The B&C idea is proposed by those personalities, they stand behind it and that idea doesn’t sound that bad after all
I have no better alternative and given the current financial situation of Nu it might become hard to continue development after a few months from now if there’s no fresh money.
Do you think people will more likely pay prices above 0.002 NBT in an auction if they “only” get NSR for that, or might they rather pay prices above 0.002 NBT if they get NSR and once it’s done BKS for them?
Nu needs to move, let’s try to find out in which direction and how
