Why Advanced Bitcoiners Should Consider Upgrading To a Shamir Backup
This is an opinion editorial by Josef Tětek, a Bitcoin analyst at Trezor.
Self-custody is an absolute must for every bitcoiner. After the collapses of FTX, BlockFi, Celsius and many others, the merit of the “not your keys” mantra is beyond obvious. However, self-custody comes in many forms, and the security properties of a single-seed setup are not that great. That is why advanced bitcoiners should consider upgrading to a Shamir backup.
What is Shamir backup?
Shamir backup is a method for securely splitting a recovery seed while adding an element of redundancy. For example, with Shamir backup it is possible to have a 3-of-5 recovery seed, where the user writes down 5 lists of recovery words, and later needs only 3 of those lists to recover the wallet. Compared to a setup based on a single list, this brings some serious benefits.
Fail-safe setup
An ordinary single-list seed is susceptible to a catastrophic loss in case a user loses the list or when a malicious actor discovers it. Mitigating both of these risks simultaneously is impossible in the single-seed scenario: the risk of loss can be decreased by creating multiple copies, but that increases a risk of theft; the risk of theft can be decreased by having a single copy, but that increases a risk of loss. Shamir backup addresses both of these risks, as there are multiple lists (decreasing the risk of loss), while a predefined amount of lists is required to recover the wallet (decreasing the risk of theft).
Geographical distribution
For Shamir to truly improve the security properties of a seed setup, the individual lists must be kept separate in different locations. This provides an additional benefit: elimination of a risk of relying on a single location. In case of securing higher amounts of bitcoin, this is something to consider, as you don’t want to be reliant on a single physical location that might become suddenly inaccessible. While such risk might seem far-fetched at a first glance, the recent experience of a Russian invasion of Ukraine proves that such risk may indeed materialize. With a sufficient geographical distribution involving locations in multiple countries, Shamir backup brings peace of mind coming from the knowledge that whatever happens, a user will be able to recover their funds.

Distributed recovery
Shamir backup allows for a distributed recovery – a wallet can be recovered without combining the individual lists in one place. The way to do that would be to successively visit all the locations with a Trezor Model T device. The device in a recovery mode remembers the progress of the recovery, so that the user can plug it in (e.g. to a power bank), enter the Shamir list, unplug it, and proceed to another location. This eliminates the risk of someone observing the full recovery seed during the recovery process – at most, they would only observe one Shamir list, which is useless by itself.
Inheritance planning
Every responsible Bitcoiner should have a plan in place to make sure that their loved ones will be able to access family bitcoin savings in case something happens. On the other hand, no bitcoiner is comfortable with the knowledge that their bitcoin is accessible by others while they are still alive and in control of their faculties. With a single-list seed, inheritance planning is tricky. Yet again, Shamir comes to a rescue.
The way to tackle the problem of inheritance planning with a Shamir backup is to distribute the lists (among family members, safe deposit boxes, an attorney, etc.), and write down a will pointing to a separate document detailing the location of the lists and the process to recover the wallet. I have described this method in greater detail in a feature article on Bitcoin Magazine. The advantage of using Shamir for inheritance planning is that you can make sure that nobody will be able to recover your wallet while you’re alive and well.
Full privacy and user sovereignty
Shamir backup, when done correctly such as with Trezor Model T device, allows for full user control and privacy. The keys never leave the offline environment and no company or other third parties know about the user’s setup. Other seemingly similar solutions such as Ledger Recover or certain assisted multisig plans require full user identification, introducing a risk of sensitive data leak, which might in turn have serious consequences for users of such services.
How to upgrade to a Shamir backup?
Switching to a Shamir backup entails creating a fresh new wallet where the funds need to be transferred to through an on-chain transaction. As with all operations involving private keys, it’s advisable to use a hardware wallet. Shamir backups were standardized for the hardware wallet use in 2017 by SatoshiLabs’ SLIP39 standard, and later implemented in Trezor Model T, as well as several other wallets. When setting up a new wallet with Trezor Model T, just choose the “Shamir Share Backup” option when prompted for the backup type, and proceed to choose a specific setup (e.g. 2-of-3, 3-of-5, 4-of-6, etc.) and carefully write down the individual lists on paper, or preferably use a more durable materials such as numerous steel backup solutions.
Editors Note: Trezor devices implement a version of Shamir secret sharing standardized by Trezor. It is not currently implemented by other devices.

How Bitcoin Will React After The U.S. Election
As the U.S. presidential election approaches, it’s worth examining how past elections have influenced Bitcoin’s price. Historically, the U.S. stock market has shown notable trends around election periods. Given Bitcoin’s correlation with equities and, most notably, the S&P 500, these trends could offer insights into what might happen next.
S&P 500 Correlation
Bitcoin and the S&P 500 have historically held a strong correlation, particularly during BTC’s bull cycles and periods of a risk-on sentiment throughout traditional markets. This could phenomenon could potentially come to an end as Bitcoin matures and ‘decouples’ from equities and it’s narrative as a speculative asset. However there’s no evidence yet that this is the case.
Figure 1: Bitcoin & The S&P 500 180-day correlation over the past five years. View Live Chart 🔍
Post Election Outperformance
The S&P 500 has typically reacted positively following U.S. presidential elections. This pattern has been consistent over the past few decades, with the stock market often experiencing significant gains in the year following an election. In the S&P500 vs Bitcoin YoY Change chart we can see when elections occur (orange circles), and the price action of BTC (black line) and the S&P 500 (blue line) in the months that follow.
Figure 2: Bitcoin & The S&P 500 outsized returns in the year post-election. View Live Chart 🔍
2012 Election: In November 2012, the S&P 500 saw 11% year-on-year growth. A year later, this growth surged to around 32%, reflecting a strong post-election market rally.
2016 Election: In November 2016, the S&P 500 was up by about 7% year-on-year. A year later, it had increased by approximately 22%, again showing a substantial post-election boost.
2020 Election: The pattern continued in 2020. The S&P 500’s growth was around 17-18% in November 2020; by the following year, it had climbed to nearly 29%.
A Recent Phenomenon?
This isn’t limited to the previous three elections while Bitcoin existed. To get a larger data set, we can look at the previous four decades, or ten elections, of S&P 500 returns. Only one year had negative returns twelve months following election day (2000, as the dot-com bubble burst).
Figure 3: The S&P 500 has performed well following election day a majority of the time.
Historical data suggests that whether Republican or Democrat, the winning party doesn’t significantly impact these positive market trends. Instead, the upward momentum is more about resolving uncertainty and boosting investor confidence.
How Will Bitcoin React This Time
As we approach the 2024 U.S. presidential election, it’s tempting to speculate on Bitcoin’s potential performance. If historical trends hold, we could see significant price increases. For example:
If we experience the same percentage gains in the 365 days following the election as we did in 2012, Bitcoin’s price could rise to $1,000,000 or more. If we experience the same as the 2016 election, we could climb to around $500,000, and something similar to 2020 could see a $250,000 BTC.
It’s interesting to note that each occurrence has resulted in returns decreasing by about 50% each time, so maybe $125,000 is a realistic target for November 2025, especially as that price and data align with the middle bands of the Rainbow Price Chart. It’s also worth noting that in all of those cycles, Bitcoin actually went on to experience even higher cycle peak gains!

Conclusion
The data suggests that the period after a U.S. presidential election is generally bullish for both the stock market and Bitcoin. With less than two months until the next election, Bitcoin investors may have reason to be optimistic about the months ahead.

Since 2020, MicroStrategy has adopted a Bitcoin-focused corporate strategy, taking advantage of Bitcoin’s potential as an inflation hedge and store of value. The company has accumulated over 252,000 bitcoins worth more than $15 billion, substantially increasing shareholder value.
MicroStrategy has borrowed money by issuing convertible senior notes to fund its Bitcoin purchases. It recently raised over $1 billion through note offerings, partly to acquire more Bitcoin. Other public companies have emulated this “buy Bitcoin” corporate strategy to take advantage of Bitcoin’s growth.
MicroStrategy’s Bitcoin treasury purchases are like a large-scale “speculative attack” against fiat currencies. By exchanging fiat for scarce bitcoin when it is undervalued, the company could reap enormous returns if bitcoin continues appreciating as a global digital store of value.
The company is undertaking the largest speculative challenge against fiat currency in history by adding the most resilient asset to its treasury. Other public companies are beginning to emulate MicroStrategy by implementing Bitcoin treasury strategies and gaining Bitcoin exposure on their balance sheets.
MicroStrategy purchased an additional $489 million of Bitcoin, swelling its corporate Bitcoin treasury to over 252,000 BTC worth nearly $10 billion. The company’s Bitcoin strategy aims to boost returns and hedge against inflation.
