Banks provide important services like savings accounts and loans. It is safest to keep savings with banks where they earn interest and can be withdrawn anytime. Banks do not provide loans against items like lottery tickets but do provide loans for important needs like homes and education. Important regulations help ensure the security of banking, like requirements for ATM passwords and KYC verification of customers. Timely repayment of loans builds good credit and allows future access to additional loans. Banks play a vital role in the economy by accepting deposits and issuing loans.
