How would you add the option to increase the token supply at any time into the contract for creating a ERC223 token and ICO crowdsale (Minting new tokens and transferring them to a desired address) ?
Just kidding. Great question, I would love to hear someone respond to this comment.
It’s definitely possible to do at the smart contract level, BCT token being an opensource example. The real question is why would you want to do that?
If the tokens represent shares in a corporate structure, you may need to do a capital increases now and then. In that case you need to expand the number of tokens to reflect the capital increase (new shares issued).
