This figure can be derived by assuming that out of the 42 million bitcoin wallet addresses on the blockchain, several are no longer in use and that many users occupy several wallets.
Emphasis mine. This is just one example of countless where I've seen "several" used in a bizarre context.
42 million addresses and "several" are no longer in use? Um... What? When I hear or read "several", I think "two, three or maybe four". Not millions upon millions as must be the case here. In fact, what do they even mean by "in use"? You are supposed to use one receive address for each transaction. That's how Bitcoin is correctly used. Re-using the same one twice is considered fundamentally breaking the protocol, although it's still done by extremely careless people, or when it's necessary due to technical restrictions, such as it being printed in a magazine for accepting donations.
Can "several" mean "any number" now? Has that always been the case? Why do they use "several" when they mean "tons" or "many"? It really pisses me off to hear words used all wrong like this, but I'm still wondering if it may be right and I've just fundamentally misunderstood the word?
Note also that they then use "several" properly just a few words later...
Several people are alive on Earth. Several stars exist in the universe. Several rocks are found around mountains.
