Twitter CEO Jack Dorsey pledged yesterday $ 1 billion of his stake in Square Pay Company, which he co-founded and chaired, to help fund the relief effort linked to the Corona virus pandemic.

Dorsey said - in a series of tweets on Twitter - that the amount represents about 28% of his wealth, and will donate it to the charity "Start Small", which he set up, which will focus later on global primary income and the health and education of girls.

Dorsey said that all donations to and from the fund would be made public to the public via a public document. Dorsey has been keen for years not to announce the details of his charity work.

Dorsey said he donates his stake in Square, not on Twitter, because he has a greater stake in the company that works in the field of electronic payments. Forbes estimates Dorsey's net worth at $ 3.3 billion.
