I’ve done a lot of reading up on crypto currencies and blockchain the past month—not because I want to invest in it, but because I find it fascinating and potentially life-changing. Just last week I was traveling internationally and I can’t tell you how many times I thought to myself “this would be so much easier if everyone was using a Bitcoin app on their phones.” I have no idea if Bitcoin is the MySpace or the Facebook of the cryptocurrency future, but it’s fun to learn about either way. One thing I haven’t seen much of is people attempting to value Bitcoin.
I’ve read plenty of logical sounding arguments for why Bitcoin will be $20,000 or $50,000 in 10 years, but those people rarely mention the discount rate that needs to be slapped on those estimates. Even if you’re a Bitcoin bull, you have to admit it’s an incredibly risky asset and there’s a chance it’s worth $0 at some point in the future. Given that, a high discount rate is required. When I value profitable, growing public companies that have little debt on their balance sheet I use an 11% discount rate. Thus, I’d say any discount rate on a Bitcoin valuation needs to be significantly higher than that—maybe 30-40%—though I wouldn’t fault anyone for going even higher.
One way to value Bitcoin is to think about what markets it might affect the most and what share it could take in each of those markets. In my opinion, it makes the most sense for Bitcoin to have a noticeable impact on remittance, e-commerce, the black market, and gold. Below are the estimated current global markets of each of those:
- Remittance – $500 billion
- E-commerce – $2 trillion
- Black market – $15.2 trillion
- Gold – $2.4 trillion (investable gold that is)
Your guess is as good as mine as to what market share Bitcoin could eventually take, but assuming it’s successful, below is one guess. Whether it’s conservative or aggressive, I don’t know.
- Remittance – 25% share
- E-commerce – 5% share
- Black market – 15% share
- Gold – 10% share
The final two factors are how long it takes Bitcoin to achieve the above market share and what discount rate is appropriate for how risky of an asset Bitcoin is. Below is a chart that shows what the current market cap of Bitcoin should be if it achieves the above market share in 5 years, 10 years, 15 years, or 20 years and then each of those values is discounted back to today at a rate between 20% and 50%.
So if you thought my market share estimates were reasonable and that they can be achieved 10 years from now (9/13/2027) and a 30% discount rate is justified, then you’d estimate Bitcoin’s market cap should be $199 billion today (vs the actual market cap which is $55 billion).
A simpler way to think about Bitcoin is to look at the global money supply ($81 trillion) and take a guess at what percent of that Bitcoin can eventually take. For reference, Bitcoin’s market cap today is roughly 0.07% of the global money supply, which is pretty meaningful in my opinion. The below three charts show what Bitcoin’s current fair value should be based on it taking anywhere from 0.1% up to 25% of the entire global money supply over the next 5-20 years. The first chart uses a 20% discount rate, the second a 30% discount rate, and the third a 40% discount rate.
Similar to before, if you think 30% is an adequate discount rate, you’d focus on the middle chart. Then, if you think Bitcoin can take 5% of the entire global money supply in ten years (9/13/27), your estimate of fair value for today would be $294 billion (again, vs $55 billion today). In that case, you’d probably be a buyer 🙂 If you think Bitcoin either won’t achieve meaningful share of the world’s money supply and/or you think it’ll take much longer (20+ years), you probably aren’t a buyer at today’s price.
It’s interesting to look at how much of an effect the discount rate has. I can’t imagine someone convincing me Bitcoin deserves a discount rate lower than 20%, but I could probably be convinced that it deserves to be much higher (50%? 60%?). In that case, it becomes almost impossible for today’s price to be justified.
Now I have no idea what discount rate is justified for an asset like Bitcoin and I have no idea what market share it will take in the future, but I think it’s helpful to look at the above charts to at least have an idea of what is baked into today’s price. In my eyes, it looks like the market is currently pricing Bitcoin as if it’s going to take notable (but not massive) market share in the world’s movement of money sometime in the next 10-15 years. It’s interesting to note that it’s very possible for Bitcoin to be wildly undervalued or overvalued at today’s price—I guess that explains that wild price swings.
Are there any readers who are invested in Bitcoin and/or are more knowledgeable about it than I am? If so, I’d love to know if anything I said is way off base.
