I hope that they introduce regulations to control all the scam coins, and maybe ICOs should go through a listing process rather like new shares. I don't see how they are going to be able to regulate reputable cryptos like Bitcoin though.
Let´s also think that ICOs are international. Each country would have different regulations and ICOs are at risk of becoming too local, like shares in a way.
If ico is regulated by some countries i only see a positive aspect. For investors it will have a reduced risk. And there is nothing stopping new icos to be like they are today, only there will be less capital for them.
Regulation normally means that you need to invest money and effort in compliance. This is usually in favour of well funded projects and can discourage the smaller, yet possibly promising projects, from taking place. Also, as laws are different in different countries, the economic burden of complying in several jurisdictions may be so high that ICOs could be only aiming for local markets.
A practical case, let´s say your ICO is trying to raise 10 million USD and you need to launch it internationally so this figure can be achieved. But for that, you would need to comply with all the regulations in all the countries. Do you see a problem with this? The fact is that the effect of regulation is already happening as many ICOs don´t accept funds from China, US and sometimes Singapore, Korea and others reducing the potential contributors. As more regulation is produced this effect may become unbearable.
