According to CoinMeta, as reported by Cryptonews, when it comes to the true cost of Bitcoin ETF, analysis indicates that fee ratios, tracking errors, and the actual returns for holders are key factors. The fees associated with Bitcoin ETF grow over time through compounding interest. The analysis covers the fee ratios, tracking errors, tax treatments, and trade-offs of self-management for 11 US spot funds. Despite new headlines about Bitcoin ETF capital flows every week, these figures obscure a more important question: What is the actual cost of ETF? The analysis shows that the true cost of ETF includes not only the fee ratios stated in the fund prospectuses but also the effects of compounding over multiple years, the tracking errors between the ETF price and the actual Bitcoin price, and the differences in tax treatment between holding ETF shares and directly holding Bitcoin. Currently, the annual fee ratios for these 11 US spot Bitcoin ETF funds range from 0.19% to 1.50%. Although the difference may not seem significant at first glance, over time, the actual amount of difference becomes considerable.
