Crypto is not about investing, its about payments. "Almost 25% of US Cross-Border Remittance Senders Use Crypto" [0] [0] https://news.ycombinator.com/item?id=32291999
Regardless, the article you link does not actually claim what the title says it claims:
> PYMNTS research reveals that many consumers (24%) see the option to send funds in cryptocurrency as a key motivator in choosing a payment services provider (PSP), in fact.
That does not mean 24% of cross-border payments are made in cryptocurrencies. It means that 24% of people think that it's important that their payments provider supports cryptocurrency as an option (and says nothing about whether or not they exercise that option, or even have an account with such a provider).
Also, even if this were true, that does not mean you are correct in stating that cryptocurrencies are about payments. It's pretty clear that far, far more people use them for investing speculation.
