Just take a look at JP Morgan Chase for example, the worlds 2nd largest bank..take a look at their financial violations since the year 2000..nearly 37 BILLION in fines.. https://violationtracker.goodjobsfirst.org/parent/jpmorgan-chase
As a financial advisor, and someone who has worked closely with banks over the course of my career, I can honestly say that banks led me to bitcoin. Banks are legitimately the reason I got so "involved" with bitcoin many years back..because I saw the centralized corruption that banks meant on this world.
Don't trust banks, ever. ( Credit Unions and small "mom & pop" banks may not fall in to this category fully ).
You have strong opinions about banks and their practices. Some banks have been fined for financial violations and fraud, as evidenced by their fines. Raising awareness about potential misconduct and holding financial institutions accountable are important. Nevertheless, banks do not all engage in fraudulent activities, and their operations are regulated. There are regulatory bodies that ensure banks adhere to certain standards and practices, and violations are punished.
Any financial institution or system should be thoroughly researched, analyzed, and evaluated based on your individual circumstances and preferences. In comparison with large, multinational banks, credit unions and smaller banks may provide different experiences and operate differently.
