First of all if you own a bank account in a good bank then you should know that its very hard to hack one's bank account, it's almost impossible unless done due to personal flaws, like sharing your key or bank account details or something ,
But still, when talking about traditional banking, i read people falling victim to phising attacks, fake microsoft employees, virusses, exploits, false invoices, money muling, vulnerable banking apps,... on a daily basis...
you know the system behind Bitcoins and the system behind banking system is same .
Could you elaborate? AFAIK, traditional banking depends on centralised relational databases and digitised tapes being exchanged between banks... This is not the same as a decentralised, immutable ledger.
Something by the name of cryptography whose Advance form is block chain . It's a complex code involving complex mathematics and the transactions are only completed through very complex and complicated steps impossible to penetrate.
The "advanced form" of cryptography is not "block chain". According to wikipedia:
Cryptography or cryptology is the practice and study of techniques for secure communication in the presence of third parties called adversaries.[2]

https://en.wikipedia.org/wiki/CryptographyWhile the defenition of blockchain is:
A blockchain,originally block chain, is a continuously growing list of records, called blocks, which are linked and secured using cryptography.

https://en.wikipedia.org/wiki/BlockchainBlockchain technology uses many cryptographic concepts, but saying that the advanced form of cryptography is blockchain is not correct (imho). It's like saying the advanced form of of an engine is a car.
