Pretty good idea to close the ICO's as they are actually becoming the viruses of crypto world.
In addition to this they shovel just keep the other tokens which are already present in the CMC now so that we can focus on these tokens and people can actually put real value to them. I mean everything will get focused on them and not the junk that is coming every other day in the market.
Then that would be the best way to run crypto currency market. ICO's are really really worst these days.
I think closing ICO is not a good idea. because there are many people who rely on the ICO project as their main income. so if the ICO project is removed, they will lose their jobs. we can avoid ICO scam more carefully in choosing ICO. or I hope in cryptocurrency there are institutions that can conduct research and eliminate ICO projects that are scam.
