Spot Bitcoin ETFs to Buy With $100 and Hold Forever

Key Points

  • The iShares Bitcoin ETF is the largest and most liquid option in the market.

Traditional-minded investors have been able to invest in Bitcoin (CRYPTO: BTC) via exchange-traded funds (ETFs) since January 2024. There are 11 spot Bitcoin ETFs on the market today, and they are pretty much the same thing in many ways. But if you want to get started with Bitcoin investing from this angle, putting a modest $100 to work for the long haul, I can't recommend all 11 ETFs.

Some of the funds are lightly traded and not widely held. Getting a fair price for these ETFs is a bit more difficult, and you never know how long the fund's sponsor will continue to manage an unpopular fund.

Others are priced above $100. Some stock brokerages will let you buy fractional shares of stocks and ETFs, but others don't. So if you have a strict $100 Bitcoin investing budget, these funds may be out of reach right now.

Being index funds at heart, most of these spot Bitcoin ETFs come with minimal expense ratios. However, a few funds charge much higher management fees, making them unsuitable for long-term investing.

These filters leave me with a short list of three suitable spot Bitcoin ETFs. These are the Bitcoin-tracking funds an intrepid long-term investor can buy for less than $100 as of May 19, 2025.

Comparing Bitcoin ETF strategies

The three funds under my microscope have delivered almost identical returns over the last year -- as expected. After all, they are all trying to match the real-time price changes of the underlying Bitcoin asset.

They do it in slightly different ways, though. The market-leading iShares Bitcoin Trust (NASDAQ: IBIT) and the smaller Bitwise Bitcoin ETF (NYSEMKT: BITB) are true index funds, basing their Bitcoin price estimates on the same price-tracking index. The Fidelity Wise Origin Bitcoin Fund (NYSEMKT: FBTC), on the other hand, generates its own Bitcoin price reports by spot-checking six large cryptocurrency exchanges. The results are similar, and both methods are robust; Fidelity just does a bit more homework than the other two fund managers.

Management fees and community donations

The iShares, Bitwise, and Fidelity Bitcoin funds all come with reasonable management fees. There are some surprises in this area, though.

You might expect Fidelity to charge a little more to cover the company's more intense Bitcoin price tracking. Bitwise and iShares simply look at an official index, while Fidelity checks Bitcoin prices at six trading exchanges every 15 seconds. But the Fidelity ETF's management fees are 0.25%, exactly matching the iShares fund's expense rate. As it turns out, Fidelity automates its more direct price-tracking system.
