BTCC CEO Bobby Lee: Bitcoin is Infinitely More Secure Than Bank Cards


BTCC’s chief executive officer Bobby Lee recently gave a talk on bitcoin security at CEIBS. In the talk, he explained that debit card PINs are six digits long, meaning that there are only one million debit card PIN combinations. Bitcoin private key combinations, on the other hand, are more numerous than atoms in the universe, at 2^160 possible private key combinations per bitcoin address. This makes bitcoin infinitely more secure than debit cards, Lee said.
