Two trackers have been suspended by the US Financial Markets constable. Bitcoin Tracker One and Ether Tracker One. The reason was some confusion among investors concerning the assets related to these trackers. Brokers that still allow trading of these financial instruments can be exposed to penalties. They were suspended this Sunday.
The first was based on Bitcoin and was issued by XBT Provider AB with an annual fee of 2.5% at the Mangold Fondkomission AB Market Maker. A total of 20 million shares have been created.
The second has the same properties except that it was based on Ethereum. With a total of 200 million shares.
