Crypto and banking defers in meters of risk, Banking system offers secured and insured policy while Bitcoin offers transparency since everything is recorded on the ledger. These two characteristics of banking and blockchain is a good combination to rapid financial transactions. Traditional banking is much more convenient to most of the people nowadays but once the crypto and banking technology combines, it will be more convenient to transact without worries.
Yes indeed, there is a huge different between banks and bitcoin in terms of risks.
With banks, one can somehow sleep through a crisis where bitcoin might keep you up 24/7. When banks offer a certain percentage of guaranteed recovery in cases of a war, a national disaster or merely a bankruptcy, bitcoin offers none. Meaning, when the whole system of bitcoin somehow collapses, we are not guaranteed anything, not even the smallest percentage of our bitcoin asset is insured and could be recoverable.
That is why till date, people like the idea of traditional banking. Moreover, when the bank account holder dies, the next of kin can claim the outstanding balance of the bank account. Unfortunately, bitcoin does not offer such official treatment. Though, one can entrust all his crypto access to a person and trust that it will be in good hands till our sad demise.
