From CoinTelegraph: Consumers are losing trust in major banks and financial service providers. Many institutional investors, traders and most millennials are moving toward Bitcoin and fintech due to the fraudulent activities and inefficiencies of existing banks.
Since most of the people who are tech savvy are millennials then it's not surprising that they are choosing bitcoin over banks because their eyes are now open to the truth of what is happening when they deposit their money to the bank. Many bank systems are compromise, funds that are suddenly gone, ATM cards copied and unexplained wealth of some people working in the bank. If people has a choice of securing their funds aside from putting it in the bank then bitcoin would be the answer.
