hi webtricks,
With the smart contract, you can directly add functionality that if the contract address receives 1 ETH, it will issue X units of your token back to the address. Everything will act automatically.
-> well, that's really smart feature! didn't know about that. and can I change the price after some time, like 1coin = 1eth and after 500'000 token sold, 1coin = 2 eth? is it possible to automate it?
