It was just the beginning!
Rulers (or governments) are trying to keep disruptive technologies under control and basically just try to utilise it for their own interests by exploiting the weaker as much as they can until the basis for realising their plans is set.
So when the infrastructure for high finance of cryptos is set, I believe they'll open up the ecosystem for the mainstream.
I think its okay if they stop those ICO's but its good that it will be regulated, screened and studied before it will be open to public. Or, it is better to fund some startup in kick starter projects as we will see the development and how the projects goes on. There are already many kickstarter startup that succeed, where its good to invest.
