I'm new to investing in ICO projects, but in one thing I'm sure it's something that is not worth investing all the money. try to invest 1 Ethereum, and if you manage to get profitably, then safely continue.
I can risk only 20% of my ethereums in a ICO project. The rest should be staying as ethereum or bitcoin so that you will be allright in a scam situation. You can't 100% trust an ICO. Some portion of your money should be okay.
