Properties of cryptocurrencies gave them popularity in applications such as a safe haven in banking crises and means of payment, which also led to the cryptocurrency use in controversial settings in the form of online black markets, such as Silk Road. The original Silk Road was shut down in October 2013 and there have been two more versions in use since then. In the year following the initial shutdown of Silk Road, the number of prominent dark markets increased from four to twelve, while the amount of drug listings increased from 18,000 to 32,000.
An active investor who has time and knowledge to hunt around for the best possible short-term debt instruments offering the best possible interest rates at their preferred levels of risk may prefer investing on their own in the various available instruments. On the other hand, a less-savvy investor may prefer taking the money market fund route by delegating the money management task to the fund operators.
To understand the revolutionary impact of cryptocurrencies you need to consider both properties. Bitcoin as a permissionless, irreversible, and pseudonymous means of payment is an attack on the control of banks and governments over the monetary transactions of their citizens. You can‘t hinder someone to use Bitcoin, you can‘t prohibit someone to accept a payment, you can‘t undo a transaction.
If you decide to invest in cryptocurrencies, Bitcoin is obviously still the dominant one. However, in 2017 its share in the crypto-market has quite dramatically fallen from 90 percent to just 40 percent. There are many options currently available, with some coins being privacy-focused, others being less open and decentralized than Bitcoin and some just outright copying it.
Cryptocurrencies have been compared to Ponzi schemes, pyramid schemes and economic bubbles, such as housing market bubbles. Howard Marks of Oaktree Capital Management stated in 2017 that digital currencies were "nothing but an unfounded fad (or perhaps even a pyramid scheme), based on a willingness to ascribe value to something that has little or none beyond what people will pay for it", and compared them to the tulip mania (1637), South Sea Bubble (1720), and dot-com bubble (1999). The New Yorker has explained the debate based on interviews with blockchain founders in an article about the “argument over whether Bitcoin, Ethereum, and the blockchain are transforming the world”.

On the borrowing end, after 10–20 years, the S&P 500 corporations become extremely accustomed to obtaining funds via these money markets, which are very stable. Initially, perhaps they only borrowed in these markets for a highly seasonal cash needs, being a net borrower for only say 90 days per year. They would borrow here as they experienced their deepest cash needs over an operating cycle to temporarily finance short-term build ups in inventory and receivables. Or, they moved to this funding market from a former bank revolving line of credit, that was guaranteed to be available to them as they needed it, but had to be cleaned up to a zero balance for at least 60 days out of the year. In these situations the corporations had sufficient other equity and debt financing for all of their regular capital needs. They were however dependent on these sources to be available to them, as needed, on an immediate daily basis.
