Having participated in the very first ICO (Satoshi Dice), and seeing the field develop - it seems they are getting more and more professional every single year.
In 2017 we will probably see the first rating agencies for ICOs, plus distributed ways of doing due dilligence. It is quite possible that in a few years the investors will be protected as much, if not more, as in traditional investment opportunities.
It will be a dofferent model though - you will have scamcoins for speculators, but also many ways of gathering information about the startups, much more accessible and sensible than the current system. This may lead to naive investors being protected/educated well enough.
Look at the internet right now. Imagine that in 1996 the government required a ton of red tape to launch websites, and would pose limits on who can access it (so your grandma woukdn't put her cc numbers on a scam site)... That's how the investment environment looks right now.
Instead what we did was to allow anyone access and publish, and fight scamming by prosecution, education and built-in browser security. People are still getting scammed on the internet daily, but it's kind of under control, and the benefits far outweighted the losses.
