We had this discussion in other threads, when US$ dollar disaster strikes NBT would be in trouble when extensively being hedged against BTC. So the best plan against that is to have liquidity against fiat (mostly USD).
Jumping from an USD peg to another peg creates some marketing challenges. I can’t buy a bread or coffee any where in the world for something equivalent of a basket of currencies. Even if USD halves in value, I think it is better to keep NBT pegged to the USD as it would stay an important denominator for a while anyway.
Preparing for a new coin (NuWorldBits?) based on a basket of currencies is something to consider, but the timing will be difficult. Now is too early, it would be seen as just another currency and won’t barely be able to compete with Bitcoin, but when dollar tumbles it is likely too late, no one really knows when that happens though.
So what kind of plan are you thinking of?
