Clear me up….Who holds it? Who uses it? Where does it go?

XRP is a bridge currency. It is to make a transaction from one currency (USD as example) and to another currency (Yen for example).

Company ABC in the US is buying something for $100,000,000 USD from Japan. In traditional finance, this takes days and is expensive. Nostro/Vostro, currency exchanges, etc….

XRP is supposed to make this almost instant and cost pennies.

If XRP was the medium for this transaction….How did the $100,00,000 turn into XRP? Who held the XRP, who moved the XRP, where did it get moved to, and who holds it at the end of the transaction?

I am not understanding the “value” of an XRP token when it appears to have an instantaneous use, and then goes into some hiding place? Can it only be used once? Is it recyclable? Who else can use it? When? How?

Just trying to visualize the value proposition for 1 XRP.

Edit: I am asking here because XRP mods keep deleting this question in /XRP and I have no idea why…
