He said he was using shares of Square and not Twitter because he owned "a lot more" of them. The shares will be sold over time, which could impact on their value and the overall size of the donation.
他说他动用Square的股票，而没用推特的，是因为他拥有的Square的股票比推特的“多很多”。这些股票将在一段时间内逐步出售，因此会影响到股票价值和捐赠总数。
Once the Covid-19 pandemic has been "disarmed", the funds will go toward girls health and education and research into universal basic income.

Mr Dorsey sought to get ahead of this charge by posting a link to a google doc which will publicly track the funds donations.
