Concentration Risk [Abstract]
Concentration Risk	7. Concentration Risk The Trust’s investment portfolio is concentrated in ETC, and its net asset value and results of operations are directly affected by the price of ETC, which has historically been highly volatile. As a result, the Trust may experience significant fluctuations in net asset value, including periods of substantial losses. This concentration also exposes the Trust to risks specific to ETC and its supporting infrastructure, including market liquidity constraints and operational or cybersecurity risks associated with the custody and transfer of ETC.

The entire disclosure for any concentrations existing at the date of the financial statements that make an entity vulnerable to a reasonably possible, near-term, severe impact. This disclosure informs financial statement users about the general nature of the risk associated with the concentration, and may indicate the percentage of concentration risk as of the balance sheet date.
