> On 8 November 2016, the Government of India announced the demonetisation of all ₹500 and ₹1,000 banknotes
> Several people were reported to have died from standing in queues for hours to exchange their demonetised banknotes.[180][181][182][183][184][185] Deaths were also attributed to lack of medical help due to refusal of demonetised banknotes by hospitals.[186][187][188]
> The exchange of banknotes was stopped completely on 25 November, although the government had previously stated that the volume of exchange would be increased after that date.
> The push for digital payments was one of the stated intentions of demonetisation.
So if someone missed this 17 days or has not managed to exchange their funds - then they would lost all their cash they were holding using demonetized banknotes.
