When you start an ICO, to receive a fund from people for your ICO, how do you choose the contract address and your wallet address to receive ETH collected for your ICO? Thank you. And excuse me for my bad English, i speak French, and i translate with Google
Usually, when doing an ICO you create a smart contract that sends the tokens when you receive ether and when you want to withdraw an amount you make a function that can be called only by the owner of the contract.
