This poster is correct, albeit not for his reasons. I speculate in digital currencies (or rather their exchange rates) and there is a fine difference.
Digital currency is an all encompassing term for any money that solely exists electronically. Example: Money deposited into a bank account is digital currency. Investing into digital currency can mean a lot of different things. A few include, taking positions on exchange rates (such as the conversion of USD to EUR), taking a position on lending yields, or even simply a position on inflation. An economically-proficient reader might opine that these are all the same things, but there is a very fine line that distinguishes them all. Sort of like the line between digital currencies and crypto-currencies.
Crypto-currencies are a subset of digital currencies. One who "invests" in crypto invests into digital currency, but one who invests into digital currency does not always invest into crypto.
There is a distinction, even if we all instinctively knew what the authors were trying to get across.
