I did a lot of research about this, but still don't understand some concepts around token price and proof-of-work.
First of all, imagine I've created a token, which is ERC20 or 223 standard smart contract, what is the best initial amount can I give it, and does it determines the price? is there any formula that can help me to understand, exactly what determines price or if it's in correlation with initial supply (and it is of course but how), how can I manage to predict approximately what will cost one my token in Euros for example?
Second, is ERC20/223 automatically PoW standard? Or I need to change something?
Third, can I modify the code after deploying on mainnet?
And for the last one, if total supply goes down and there is nothing left to mine, is minting the only solution?
