| Factors Affecting Performance [Text Block] | How did the Fund perform in the last year? The Fund is an actively-managed exchange-traded fund (“ETF”) that seeks long-term capital appreciation by investing under normal circumstances, at least 80% of its net assets, plus the amount of any borrowings for investment purposes, in equity securities of U.S. and non-U.S. “Blockchain Companies”, as defined below, and in long positions in U.S. listed bitcoin futures (“Bitcoin Futures”) contracts. Under normal circumstances, the Fund will invest at least 25% of its assets in Blockchain Companies and will have notional exposure to Bitcoin Futures equal to at least 20% of the total assets of the Fund. Blockchain Companies include companies that derive or are expected to derive at least 50% of their revenues, operating income, or assets from digital asset mining, blockchain and digital asset transactions, blockchain applications, blockchain and digital asset hardware, and blockchain and digital asset integration, as defined by Solactive AG, the provider of the Underlying Index. Blockchain Companies also include U.S.-listed operating companies that directly own a material amount of digital assets. For the 12-month period ended October 31, 2024 (the “reporting period”), the Fund increased 111.98%. The Fund had a net asset value of $38.09 per share on October 31, 2023, and ended the reporting period with a net asset value of $71.47 per share on October 31, 2024. During the reporting period, the highest returns came from CME Bitcoin Futures and the Global X Blockchain ETF, which returned 180.29% and 120.36%, respectively. The Global X 1-3 Month T-Bill ETF returned 5.38%. The Fund delivered positive returns during the reporting period, primarily driven by continued positive sentiment toward digital assets, specifically Bitcoin. The U.S. Federal Reserve's decision to cut interest rates by 50 basis points in September 2024 provided tailwinds to risk assets, including digital assets. Additionally, investor sentiment has improved as the rate cut signaled growing confidence in the U.S. economy by the Federal Reserve. The U.S. Securities and Exchange Commission’s approval of spot Bitcoin ETFs in early 2024 also boosted investor confidence and drove up the value of digital assets. Furthermore, advancements in blockchain infrastructure and scalability solutions that enhanced the practical applications of blockchain technology positively influenced the Fund's holdings during the reporting period. |

| Factors Affecting Performance [Text Block] | How did the Fund perform in the period? The Fund seeks to provide investment results that correspond to the price and yield performance, before fees and expenses, of the CoinDesk Bitcoin Trend Indicator Futures Index (“Secondary Index”). The Fund is passively managed which means the investment adviser does not attempt to take defensive positions in declining markets. The Fund generally seeks to fully replicate the Secondary Index. The Secondary Index is designed to provide exposure to a strategy that systematically and dynamically allocates between exposure to U.S. listed bitcoin futures (“Bitcoin Futures”) contracts and cash based on the Bitcoin Trend Indicator (“BTI”), a signal which conveys the direction and strength of the current price trend of Bitcoin. Bitcoin is represented by the CoinDesk Bitcoin Futures Excess Return Index (Ticker: BFIC) and cash is represented by the passively-managed Global X 1-3 Month T-Bill ETF (Ticker: CLIP), an affiliate of the Fund. Since March 20, 2024 (the “reporting period”), the Fund decreased by 20.60%, while the Secondary Index decreased by 15.70%. The Fund had a net asset value of $33.10 per share on March 20, 2024, and ended the reporting period with a net asset value of $26.09 per share on October 31, 2024. During the reporting period, the Global X 1-3 Month T-Bill ETF returned 3.28% while the CME Bitcoin Futures returned -76.21%. During the reporting period the Fund recorded negative performance. Even though Bitcoin Futures have exhibited positive performance, driven by a confluence of factors including halving events, institutional adoption, regulatory advancements, technological innovations, and macroeconomic factors, the Fund’s trend strategy resulted in allocations to cash (represented by the Global X 1-3 Month T-Bill ETF (Ticker: CLIP)), which became a drag on performance. The approval of spot Bitcoin ETFs in early 2024 boosted investor confidence in Bitcoin Futures and drove up the value of digital assets. This approval led to heightened institutional participation which greatly enhanced market liquidity and stability. While the strategy underperformed during the period, these tailwinds for Bitcoin Futures, alongside the dynamic allocation strategy of the Fund, allowed investors to access Bitcoin Futures in a risk-managed basis. |
