Debit card has the same protections as your credit card as long as you don't give away your pin.I have a debit card and I never use it. I always use a credit card and pay it entirely every month. If my debit card gets hacked, that's my money. If my credit card gets hacked, that's someone else's money.
Cash makes you think differently. And the government nor the banks can turn off your cash electronically.
