ICO regulation is good in my own opinion because it will help to reduce scam projects that's currently rampant in cryptocurrency industry, it will also to reduce a lot of low quality projects.
Yes right, the presence of ICO has been very important to make investors trust again to put their money at ICO, 2017 is the best year for ICO, many projects have successfully achieved hardcap even when pre-sale, but unfortunately this is used for scam, regulation will stop scam projects.
I think 2017 was the best year for ICO, but it was not the last good year. Now with the advent of IEO, many projects have also begun to collect large amounts of money. I think good times will come again
