Now, in English. I have never invested in ICOs and I don't think I will. Mainly, for the following two reasons:

• HIGH UNCERTAINTY I like investing on cryptos which has been on markets for, at least, a few months. When I invest on Stocks, I never buy after IPOs. I'd rather wait for a minimum of two quarters to see how the stock is going. In cryptos I try to emulate that behaviour.
• DIFFICULTY TO UNDO DE OPERATION. If any of the hypothesis of the research changes after investing on a crypto, I can sell it, undo the operation and search for another crypto to invest my resources. For instance, if the roadmap is changed, or if a key advisor leaves the project. If my money is in an ICO, I can't get it until the crypto is listed on a exchange.

Anyway, if you are interested in ICOs, you might use some of the advises of this post in your investment.
