In a debate with my friend. I stated "I bought some bitcoin" and "I have some bitcoin".
My friend argues this is a completely incorrect usage of "some" before a non-plural noun. In fact, my friend says that the use of "some" is completely misleading since I don't actually own multiple bitcoins or even a singular whole bitcoin. I'm arguing that it's a perfectly reasonable usage just like I might, "have some pie", I have some bitcoin.
I think at worst it's simply an informal usage case, but one I hear daily with the current popularity of crypto-currency.
Thanks in advance for some outside perspective!
