Hi, Im looking to understand ERC2 tokens a little better.
Could someone explain to me how Token Bonuses are actually managed?

If there is an exchange rate within the smart contract, how do you get around it and offer, say, 20% or 50% bonus, as most ICOs do?

@eryssonbarros
how do I update a smart contract and assign a new administrator ?
Does anyone have any tutorials?

@DataGuru9
@eryssonbarros sorry if my suggestion looks childish but can you not create a function to make new msg sender as the owner and take old contract into new one using inheritance etc
