Also, could you explain the dynamics of Paycoin? How does it work that everybody can stake 400% per year in cashtakers and the money supply is unlimited. Where does all the cash come from and why?
... explain the dynamics of paycoin?... You'd have to be more specific. I'm not going to write a dissertation on the paycoin economy.
How can everyone stake at 400% per year? It's easy... that's the way the algorithm is setup to do so. You have to remember, they are not giving you USD... but paycoins. So they aren't giving you real money, just fake internet money that could be exchanged for USD or BTC at whatever the rate is for that moment.
It's their belief that the value of this exchange should be kept from tanking due to their cash reserve, where they can buy all the dumped coins at $20 to keep the value stable.
Where does all the cash come from? It came from the customers themselves! People buying hashlets directly, their 10% cut of market sales, hashstaker sales, etc.
How many coins will there be after PoW?
12.5 million according to the whitepaper.
What about after 1 year of PoS?
Unknown, because coins are released in paycoin's POS scheme based on demand. It's not a steady flow like in other coin's POS schemes. The more demand there is for the coins, the more coins will be minted by the prime controllers via their staked coins.
When will PoW start? Where can it be mined?
At the end of what would have been round 3 of the ICO. The details of where it can be mined have not been released yet.
When will the wallets be released?
Standard wallet software will be released when the coin goes live. All this is standard stuff for a coin release.
Where can we exchange Paycoin on the exchanges? On which exchanges?
