I tried to run @mhps' calculator (https://github.com/mh001/buybackcalc)
but it failed with error code
"Failed to get balance from http://blockexplorer.nu/api/addressInfo"
So I base my calculation on information that's a bit over two weeks old, which should be enough for the cause.
With a NSR sell rate of 2 M per day and expecting that the rate will stay near 60 Satoshis, the NSR sale provides Nu with 1.2 BTC per day.
At current BTC rate the 496,611 NBT equal 822 BTC or 635 days of NSR sale.
It will take only close to 2 years to gather enough BTC to back the NBT in circulation.
Don't you see how ridiculous that is?
Oh, by the way this sale would add 1,370 M NSR to the NSR in circulation, which would more than double the amount of NSR in circulation.
It's pretty safe to say that continuing the NSR sale over almost 2 years will push the NSR price below 60 Satoshis.
After having lived off the assets you received for selling NBT (customers), you now live off selling NSR (shareholders).
Go and get revenue!
I seriously ask: where shall that lead to?
What's the point you are trying to make?
That you can keep the system running for some more time until it finally collapses?
Are you still dreaming of a "liquidity (consuming) engine" or will you transform this into a business?
I know... doom, gloom, negative, write on paper, flush down toilet.
I will somewhere along the way stop writing here. But I'm not doing you a favor when I stop. I'm doing you a favor now.
So you are proposing to skin customers and shareholders once again - just in case you find customers who buy NBT from Nu?
Needless to say that anybody who has enough funds could easily buy cheap NSR now, buy NBT later, see the BTC being wasted on NSR buybacks, sell the NSR in the buybacks, dump NBT on the market, wait for the peg to break and buy cheap NSR once more when Nu stubbornly makes the same mistake again.
Rinse and repeat.
Does that sound familiar?
