If you were able to transfer apple shares between people like bitcoin and there are people that's accepting it as a payment method, then I guess that qualifies as a currency. In a way, the amount of bitcoin that we hold is just like a "share" on the amount of all the bitcoins in circulation. Just like fiat, the value of our fiat depends on how much fiat there is in your country
No, this doesn't qualify as a currency
You can transfer real apples (which you eat) just like you transfer banknotes and coins, but does it make apples into a currency (even if we assume that apples don't rot in a few days)? I guess it doesn't. To have properties required for circulating as a currency is evidently not enough to be a currency. What makes something into a currency is its universal use and acceptance as a means of payment for the exchange of goods and services. So even if you could transfer Apple shares just like you transfer bitcoins, that alone wouldn't make them into a currency (a money token). These shares should actually be used for transferring value to be rightfully called a currency. The word itself ("currency", i.e. circulation) tells it all
You didn't see the "if it's accepted as payment method" in my post, don't you? Because what you're telling is basically what I told from that short note. When something is accepted by people, then it will be qualified as a currency, not because it's easy to transfer the "thing". Let's say that oranges are accepted by people as payment method because everybody loves oranges and you can easily trade oranges to a commodity, then that will qualify as a currency (like I said in my previous post).
I don't see how else something will become a currency (measure of value or payment value) other than it being accepted as payment method. You can create a dupe of money but with different logos, since no one is accepting it, it's nothing but a piece of paper. Even the paper money that we're using is literally just a piece of paper. It became a currency because people are accepting it as a payment method.
