Regulating the ICO market means that businesses would become legally obligated to deliver on the mission and business plan they set out during the ICO. So, there would be less incentive to change plans and take greater risks, providing assurance for investors.  In the case of hacked ICOs, investors would also be able to claim some of their money back under a regulated scheme, similar to IPOs. These assurances are likely to attract more investors with greater capital holdings, potentially helping ICOs raise even greater funds far quicker. In my opinion, Regulation of ICO will have positive influence on the ICO.
