This WSJ article is the first mainstream financial article that I’ve seen discuss the high interest rates paid on Bitcoin and stablecoin (cryptocurrency backed by a “stable” asset like the US dollar). I am (again) not a cryptocurrency expert, but it does seem appropriate to educate and warn other curious investors about the risks. Here’s my take:
- The price of Bitcoin can vary a lot. It probably went up or down by a hundred dollars in the time you took to read this sentence.
- Stablecoin prices tend to vary less because they promise to be backed by a stable asset. USDT (Tether) and USDC (USD Coin) are both currently trading exactly at US$1.00, so it appears that the market believes this claim. However, US dollar stablecoins are not affiliated with the US government or any central bank.
- Brokers/exchanges where you can buy and sell these cryptocurrencies are not backed by government insurance. They are businesses – some will end up worth billions, some will get bought by a bigger competitor, and some will probably fail (likely because they were hacked). Even though they might be called “savings” or “interest” accounts, no cryptocurrency is held in an FDIC-insured bank, or even an SIPC-insured brokerage account. They will promise to keep your crypto safe and pay interest, but it is possible they may not live up to their end of the deal, AKA “counterparty risk”. Not every exchange is equal.
- This potential risk is a big reason that they have to pay you 6% annual interest in your Bitcoin and/or 9% annual interest in your USDC stablecoin. They are lending out your assets and earning even more interest, because traditional banks won’t do so.
- The result is two separate risks – the risk of the price of crypto itself, and counterparty risk of the place holding your crypto.
In the end, I agree with this part of the article (even with the mocking tone):
If you’re a risk-taker who relishes the ride when an asset soars and can laugh off the losses when it crashes, then maybe you should consider letting a broker borrow your cryptocurrency at a generous rate.
After all, if you aren’t troubled by the extraordinary volatility of virtual money, you might as well earn some interest on it.
I did buy some crypto a few years ago as a purely speculative investment and to promote my own learning. We are talking less than 1% of net worth, but it has become a 5-figure amount. I was very skeptical at first, but now I am partial to the theory that either BTC is worth zero, or it will eventually be worth at least on par with the market cap of gold (roughly $200,000). I accept that both scenarios are possible.
I bought Bitcoin using the Voyager app ($25 bonus, publicly-traded with $3 Billion market cap) and also opened an account with BlockFi ($250 bonus, just completed $350m Series D at $3B valuation). Both of these companies are worth well over a billion dollars and gone though various rounds of funding, which isn’t bulletproof but it means that smarter people than me have vetted their security protocols and business practices.
BlockFi pays me 6% interest on up to 2 BTC (8.6% on USDC) and Voyager pays 6.25% interest on BTC (9% on USDC). I reinvest the interest so that I own a little bit more BTC each month. However, I fully accept that I am getting paid this interest and getting the convenience of buying BTC with a few taps in exchange for the potential risk that they will go bust while losing all my BTC. There are other options like hardware wallets, but I am don’t want the inconvenience or to worry about forgetting my bitcoin passwords for my relatively small investment.
Bottom line. Sorry, you can’t earn a 9% “safe” interest rate on your cryptocurrency, even if it is a US-dollar backed stablecoin. At a minimum, you still have counterparty risk. This is a business lending out your assets, charging interest, and giving you a cut. They can go bust, and not all exchanges are the same. Perform your own due diligence when picking a broker/exchange to buy from. I picked what I think are among the safest, but it’s still risky.
Even though the interest rates are quite low, I keep my “safe” cash in FDIC-insured bank accounts and similar.
Although I’m still decades away from Social Security, I see a constant stream of articles about the “best” time to start taking benefits. Often, you are told to delay claiming until age 70, as you will receive a more valuable, inflation-adjusted, government-guaranteed payout for the rest of your life. But if you have a spouse, it may be better for one of them to claim as early as possible, at age 62. There are many calculators out there – here is one 
Perhaps it is because I somehow ended up buying $5,000 in gold coins a couple weeks ago, but I’ve been doing some reading about gold again. The stock market is at higher and higher valuations, while the Fed promises that interest rates will stay low for a long time. The real yield on TIPS remains negative, meaning that it is highly unlikely that any high-quality investment-grade bonds will beat inflation over the next decade. Is there really no alternative?







Here’s my monthly roundup of the best interest rates on “safe” cash as of March 2021, roughly sorted from shortest to longest maturities. I keep 12 months of expenses as part of my semi-retirement cashflow planning, and there are many lesser-known opportunities to improve your yield while still being FDIC-insured or equivalent.

When creating financial statements, there are “generally accepted accounting principles” (GAAP) so that all companies follow the same standardized set of rules. After reading 100+ books on personal finance, you could also create what I would call “generally accepted personal finance principles” (GAPFP?), as organized into a 









When talking about constructing an investment portfolio, you’ll often hear about diversification and buying low-correlation or non-correlated assets.
