I think this is the beginning. Most altcoins end in failure and causing trouble to some investors who don't calibrate accurately the risks. Regulation maybe the key for the future of altcoins. Japan, despite rumors of ban ICOs is studying regulation:
Although Japan has no specific laws for ICOs, they may be regulated by two existing laws. For businesses launching an ICO, the FSA emphasized:
ICOs may fall within the scope of the Payment Services Act and/or the Financial Instruments and Exchange Act depending on how they are structured.
If a token issued in an ICO falls under the virtual currency provisions of the Payment Services Act, then businesses providing digital currency exchange services regularly “must be registered with each Local Finance Bureau that is the delegated authority to the Prime Minister,” the FSA wrote. So far, eleven cryptocurrency exchanges have been approved by the agency.
However, “if an ICO has the characteristics of an investment, and the purchase of a token by a virtual currency is practically deemed equivalent to that of legal tender, the ICO becomes subject to regulations under the Financial Instruments and Exchange Act,” the agency described.
