“Anything you can use a credit card for - and by transferring it to your checking account, anything you desire and can afford.”
What is the ‘transaction fee?
Depends on how you liquidate
While you never see them, there are transaction fees on every credit card or debit card transactions. Your bank collects the fees for debit cards from the vendor. Your vendor is also paying Visa (and the others) a fee for every transaction. Its built into the price of the product/transaction.
Bitcoin or Crypto transaction fees are usually lower.
Last year I moved more than six figures of bitcoin halfway around the world for $12. You are not going to get the speed and tranx cost for that kind of move from a bank.
