Imagine NXT as a SC, all big holders of Bitcoin could put there BTC there and earn interest. The fees could be cheaper than Bitcoin.
I am not a fan of PoS but I hold NXT for other reasons.
Why? This is where a centralized coin (Phillipines) as a SC would put with BTC as the basis of the coin. POS system for a centralized coin makes absolute sense, and we could lower the transaction costs for usage assuming our Miners Rate gets high in their currency, also prevents bloat.
FUCK NXT
And this is good for Bitcoin how?
It will eat Bitcoin like Fiat ate Gold, a PoS SC is a terrible idea, it will reward wealth not productivity.
