Cryptocurreny world definitely needs a regulation. Today many people are introduced to bitcoin and altcoins hoping to profit some gains looking at the rising charts and news. However most of them lose their money because of investing scam altcoins, or panic trading.
Chinese ICO regulation attempt is the first step of this change. I am sure other countries will follow and will not let the cryptocurrencies do what ever they want.
This may make volatility in pricing, and this will be a reason for an upcoming correction. However, these regulations may help cryptocurrencies to be mainstream.
The altcoin market really needs strong regulation, otherwise is it not that anyone can do ICO, including most crooks?
However, altcoin itself is the product of decentralization. If regulation is the case, then change will be centralized. This runs counter to Satoshi's wishes and contradictions.
I personally still look forward to an ICO convention.
