I would recommend to spend your 5 ETH into two variants, first - to stay in ETH, and second - to buy 4 coins from the top 10 coins that fall down in price per every ETH, but not to invest into ICO, nowadays there are few good of them.
Yes 5 ethereum is not a very large amount to invest, so the best option would be to buy coins from existing and promising startups that at least follow the roadmap.Yes, for the analysis will need to spend time, but it's worth it.If you still want to invest in ICO, then in my opinion this project looks promising:
