Depending on the person too, they might stick around waiting for the transaction to get at least one confirmation, so you find yourself making bitcoin small […]

Users whose data is very sensitive, and credit card company who want enough user data to mitigate fraud. A service site like Ashley Madison is subject to high charge backs. […]
