SEC: Ether is OK, but ICOs are toast

After months of speculation and debates, the SEC's William Hinman, head of the Division of Corporation Finance, finally opined on Ethereum. Speaking at the Yahoo All Markets Summit: Crypto conference in San Francisco, he said that many, if not all, ICOs would be classified as securities. "Central to determining whether a security is being sold is how it is being sold and the reasonable expectations of purchasers," he told the crowd.

The cryptocurrency market rebounded immediately. Ethereum has increased ~9% as of the time of writing, but there's no reason to celebrate for the teams who launched tokens on top of the network.

The last one has some inconveniences, but we aren’t forced to use them — after all, if we want we can continue using normal multisig schemes with separate, non-aggregated signatures and still gain something."
