The are chances that a bank may close one day. It can happen due to various reasons.
In United States, The Federal Deposit Insurance Corporation (FDIC) preserves and promotes public confidence in the U.S. financial system by insuring deposits in banks and thrift institutions for at least $250,000
In India , What is the maximum deposit amount insured by the DICGC?
Each depositor in a bank is insured upto a maximum of Rs.1,00,000 (Rupees One Lakh) for both principal and interest amount held by him in the same capacity and same right as on the date of liquidation/cancellation of bank's licence or the date on which the scheme of amalgamation/merger/reconstruction comes into force.
So as an Indian, if ( money > 100000 ) then open more accounts++ :))
