1.Only invest what you can afford to lose.
2.Never invest in something you dont understand.
You wont immediately understand everything, thats ok. Do some research.
3.Dont day trade unless you spend a minimum of 6 hours a day on the markets.
4. Be patient and buy it on sale.
You said it all as an investors you don't just invest on any ICO you have to make research and also don't invest what you can't afford to loss because investment is a risky game, the percentage of making profit is less than that of profit. The number one thing that shouldn't be ignored is patient for every successful person he/she needs to be patient. I think your update will enlighten and serve as a guide to people before investing on ICO.
