Blockchain For Charity

1 of the many ideas I have had for blockchain is using blockchain for charity.
As many of you know, there is lots of issues around the world and that helping lots of people can be quite expensive. By using blockchain, multiple people can contribute towards charity and in turn, they can be given more incentives based on how much they invest (e.g. 1-9 tokens is a common collectible, 10-99 tokens is uncommon collectible, 100-999 tokens rare is a rare collectible, 1000-9999 is a super rare collectible, 10,000-99999 is a hyper rare collectible, 100,000 ultra rare).
charities are all internationally / nationally recognised charities (for example, in the UK, people can only contribute towards charities registered with the charity commision).

any ideas on how I could improve this?
