A few things I could like about PoS. The premine wallet/wallets could set up a level of security if always running. It would also generate coins I hope would be used at least 90% for giveaways. I would like legit promises they would be doing so, though.

It would also stop more Nyan from being produced faster than there are buyers. Counter to this, a fiat/Nyan exchange might help PoW accomplish nearly the same goal with a halving before the launch of the exchange. Though that exchange could equally help PoS.

So with PoS, what interest rates are we talking? Over how long? If I remove or add coins from my PoS wallet, will it stop earning coins for a while? I heard some coins require holding wallets. How many coins would it generate versus what is generated curently?
