When you refer to bitcoin as a "store of wealth" do you mean that a bitcoin will retain its value over time? Which bitcoin do you mean, some coin you recently minted or one that's from a hacked exchange and hard to cash in because it's tied to a known crime? Is this a bitcoin you have in a cold wallet somewhere? Are you running a connected node with the intention of exchanging your bitcoins with someone else? Or is your "bitcoin" just an entry in an exchange's ledger somewhere, in that case is it a bitcoin or just faith in that exchange? Is a bitcoin a store of value in the same way a bag of uncut diamonds is a store of value?
