Yeah it's tricky when you are first starting as you need to have a crypto to initially invest plus a wallet to hold the final product in.
First thing is to find a safe place to purchase bitcoin or ethereum. I would personally stick to the big companies.
If it's an ethereum token that you will eventually receive and the ICO doesn't have it's own wallet then I recommend MyEthereumWallet or as it's often called MEW.

Do your research though and only invest what you can afford to lose.
