Could someone guide me on writing a smart contract? I think what I am looking for isnt so hard, willing to pay if necesary, sorry if this post isn´t allowed here. I read the FAQ And couldn´t find anything that said this isn´t allowed.

@novumhouse & @yungsarria please refer to ethereum.org and read down, it will introduce you to contracts with a starter token dapp.

how can i offer 10% of my custom-token to investors during ICO? Eg -> invest now, when myToken is minted later, 10% gets split proportionally between investors
contract InvestorContract { ... 
// addresses of investors
mapping (address => uint256) public balanceOf; }

function contractEnd() {
    // logic to split investor shares into MyToken ?
}

solidity is quite easy to pick up but i have not found much info beyond the basic templates yet
there are still a few things i don't understand
like, do I need to run a full node? and how much eth should a contract store - and does this pay for the gas transactions of users or do they pay themselves?

Does anyone know why starting my coin using the directions from Eths website is not compiling?
Undeclared identifier.
if (balanceOf[_from] < _value) throw; // Check if the sender has enough

Are _value and _from accessible to the current function?

depends what you want to do, the courses i saw helped me set up a private network but tbh ive learnt more from the docs
i grabbed 2 of them for a tenner each, not worth significantly more imo

Hello! I tried to upload ETH via bitcoin in Ethereum Wallet, send it to adress that was shown, but closed the window with adress before I recieved ETH, so it was about 8 hours ago, and I still haven`t recieved it. Maybe someone had the same problem? Thank you
