Bitcoin fractional shares: Can you buy fractional shares of Bitcoin?

Conor Scott, CFA| Updated December 2nd, 2023

Nearly every investor knows about Bitcoin (BTC), the world’s largest currency by market capitalization. Its rapid rise to fame overshadows its humble and anonymous origins even as its creator Satoshi Nakamoto refuses to reveal his true self. And a single bitcoin almost always costs tens of thousands of dollars. 

Enter Bitcoin’s fractional shares. A minimum Bitcoin investment is nowhere near $10,000. It’s possible to invest $10 in Bitcoin, or $100 if you’re feeling confident, through the option of fractional shares. These are sometimes referred to as partial shares, but both terms refer to trading decimals of a whole.

Yes, it’s possible to receive fractional shares of Bitcoin or buy “partial Bitcoins” with a minimum Bitcoin investment of $10 or less. The absolute minimum is defined by your online brokerage. We’ll get to this further in the article. 

What is a satoshi, or a fraction of a bitcoin?

The average BTC investor owns approximately 0.2 BTC or less. The smallest unit of value with BTC is a satoshi or a “sat” for short. There are 100,000,000 sats in a single bitcoin.

Taking a hypothetical example, one sat is worth $0.001 if one bitcoin is worth $100,000. This is how you can invest $100 in Bitcoin or even $10. Fractional shares of Bitcoin sustain the initial guiding ethos of Mr. Nakamoto–decentralized finance for all. 

What is the minimum amount of Bitcoin you can buy?

The satoshi remains the true, theoretical minimum of Bitcoin you can buy. However, since this amount is lower than a single penny, online brokerages have implemented their own arbitrary minimums. 

For example, Coinbase requires at least two full units (i.e., whole dollars) of your local currency. eToro requires $10 for US-based customers. Different brokerages set different rules.

They currently offer 60+ options of cryptocurrencies, and the platform is intuitive and easy to use. When buying cryptocurrencies, you will gain ownership of the asset if you fulfil three requirements:

  1. There was no leverage on the position through CFDs;
  2. You did not short-sell the crypto asset;
  3. You are not a client under the supervision of the Australian Securities and Investments Commission (ASIC).

If you are a client of eToro Europe, you can withdraw some of the cryptocurrencies from the platform to the eToro money crypto wallet and transfer them somewhere else if you wish.

The platform also allows you to leverage your cryptocurrency position through a Contract for Difference (CFD). This financial instrument is a derivative that lets you open a position without owning the underlying asset, benefiting from a higher rate of return than what you could gain initially, but exposing yourself to higher losses.

Coinbase is one of the biggest cryptocurrency exchanges in the world, with more than 100 million registered users.

For more advanced traders, the exchange enables the Coinbase Pro, which any retail investor can use to have more advanced types of trades, such as limit and stop orders, which are unavailable on the central platform.

While Coinbase is known for its simplicity, the platform has higher transaction fees than its competitors. Users also tend to complain about its customer service, saying that it is hard to contact other humans, with the service being primarily automated. Finally, Coinbase Europe is not a regulated financial service provider for digital currency services.

Founded in 2011, Kraken is one of the oldest crypto exchanges in the world. You can easily buy/sell over 185 cryptocurrencies with low fees (up to 0.26%), versatile funding options, 24/7 customer support via live chat, and high-security standards. You can buy bitcoin fractional shares starting with as little as $10!

It offers trading tools for beginners, scaling up to that needed by experts. In addition, there are detailed “Crypto Guides” alongside instructional videos, even a podcast if you’re so inclined. These are excellent tools for beginners to be informed before making any decision.

We like the inclusion of futures and staking. The latter functions are similar to a locked savings account. With the right cryptocurrency choice, you could earn 10%-plus in interest. It’s an ideal choice for traders who wish to keep a portion in a secure wallet but make something out of that too.

On the downside, It lacks a wallet for retail users, but it maintains a reputation for storing 95% of the exchange’s assets in cold storage across different geographies. Besides, Kraken’s trading platform and mobile app are pretty basic, so you might be disappointed if you’re looking for more advanced features.

If you are beginning to invest, you may be overwhelmed by this platform’s interface and opt for other exchanges that are more user-friendly, even though they have higher fees for trading. If you have some experience and want to access a platform with low fees and an extensive list of assets, Crypto.com might suit your needs.

Is there a downside to buying fractional shares of Bitcoin?

Yes, there is one key downside to fractional shares: fees. Online brokerages tend to charge flat rates for small crypto transactions, in addition to any variable spreads between dealer prices and prices you receive. 

So if you trade $5.00 worth of sats, your brokerage may charge a flat $0.99 trading fee (like a service charge) in addition to a hypothetical spread of 2.00% and other service fees. A spread manifests through the difference in the bitcoin price you receive against what your broker receives. Since they’re offering a slightly higher price to purchase than the market, you receive fewer bitcoins. 

The core problem: you lose a significant percentage, in this example at least 20%, of your investment to fees due to fractional share trading.

The bottom line

To sum it up, these are our top picks:

Best platforms for Bitcoin fractional shares

#1 eToro Best Overall
#2 Coinbase Best for beginners
#3 Kraken Best for low fees
#4 Crypto.com Best for rewards and crypto card

Fractional shares of Bitcoin remain a core necessity for all crypto traders and investors worldwide. Otherwise, many would be left out of the market due to Bitcoin’s supply cap of 21 million coins and its price going into the tens of thousands. 

The minimum amount of fractional shares you can buy is determined by your brokerage since a single satoshi still holds a value of less than a single US penny. Further, trading fees consume significant portions of small crypto investments–making the task of choosing the right broker all the more critical. 

This is why we have included an in-depth review of the best platforms above for you. We want you to make the right choice for you, and turn a profit from your first Bitcoin trade!
