Regulators have issued a new warning to investors in the Netherlands about putting money into initial coin offerings (ICOs).

The Netherlands Authority for Financial Markets (AFM) – the country's equivalent to the U.S. Securities and Exchange Commission – published a statement today outlining the risks it sees in the market for new cryptocurrencies, including those issued through the blockchain funding model.

Merel van Vroonhoven, chairman of the AFM, said in a statement:

The regulator went on to enumerate a number of possible concerns for investors, including a lack of transparency into some ICO organizers. AFM also warned investors to be wary of promises of high returns, as well as the risk of price manipulation in token markets that have low levels of trade velocity.

In a follow-up statement to CoinDesk, a representative for the agency called for greater cooperation among regulators on the issue.

"At this moment we have sent out this warning as have other supervisors in Europe. As ICO’s are international phenomena’s and reach out to consumers/investors cross border, it is important we cooperate with the other European regulators," the representative said.

The release is the latest from a national-level securities regulator, adding to the growing chorus of concern from agencies in countries like Canada, Singapore and the U.S. In some cases, as seen in China and South Korea, market watchdogs there have moved to prohibit use of the funding model entirely.

The European Securities and Markets Authority, one of the primary markets regulators for the European Union, issued similar warnings today. The AFM does not have the ability to regulate ICOs, according to Dutch News.

Approximately $3.3 billion has been raised through the ICO model to date, according to the CoinDesk ICO Tracker.
