Iran experienced one of the worst flood and the total destruction to life and property is estimated to be roughly 2.5 billion USD.
Iran economy has been crippled by the US sanction, which further crippled the relief attempts as well.
This has lead to the local crypto community to set up a donation portal through which people all over the world can donate for the flood relief.
The decentralised nature of the cryptocurrency makes it impossible to control or supervise by any central authority.
This allows people to donate anonymously and quickly inspire of the challenges.
