God owns everything in the heavens and on earth, that's including the coins, like you quoted Scriptures, silver and gold is his. Likewise Bitcoin. But from your post I can deduce the word "god" which isn't referring to the Almighty God, so who were you talking about?
How can you know that? Just because? Did he tell you that? Is it written somewhere? Stop saying "it's god" to every argument, it's stupid and ignorant.
