After almost two years operation of Nu, here is my summary:
1) Hardcore Function Sustainability(profitability).
Bitcoin's hardcore function is mining, because mining activity itself is probably profitable, people are driven by internal incentive to do so, in fact the criticises focus on PoW is exact the profitability(sustainability) of mining in future.
Nu's hardcore function is liqudity providing, because strict pegging itself(NBT/BTC NBT/USD) is not (enough) profitable at all, Nu has to compensate LPs which means high expenditure and run out of fuel within 2 years, Nu has much worse sustainability than Bitcoin.
2) Encourage people to hoard currency
Bitcoin encourage it by fixed quantity of 21million, and people are driven by internal incentive to hoard, sometimes, some of them earn a lot, sometimes they lose, but the speculation chance is there, lots of BTC have been kept by the public.
Nu's strict pegging USD token has no incentive to hoard, seldom people will keep a continuous devalued paper money.
Therefore, Nu has done very badly on this two fields, if Nu has a future, it must provide profitable liquidity providing business and induce people to hoard NBT. Use loose pegging making LP as a profitable business, and add anti-inflation feature to NBT, because people love anti-inflation money said by Hayek.
If you guys continue to do business on "Rape Mode", i.e Provide liquidity with force(expenditure), let people hoard NBT with force, otherwise decrease their balance, you will fail this business. The right way is "Seduce Mode",
: just like Satoshi's style.
Conclusion: before any smart community launching a Hayek money, Bitcoin is always the best!
