The dollars in your checking account are only electronic entries in a database. You don’t think there is actually cash sitting in a bank, do you?
Can I do that with bitcoins?
Most certainly there is cash in the bank. At least enough to cover what piddly amount I keep in there. I get the whole frqactional reserve scheme, but if I want cash today, I can get cash today. Tomorrow? That’s another question / argument.
