title_body: Why is there a minimum amount of ADA required to vote for Project Catalyst proposals?
upvoted_answer: As Dor Garbash mentioned there are several reasons:
  
  performance - the reason why they delayed Fund4 is that now the engineering team is working to improve the overall processes so that more people can participate
  fraud - to prevent people who don't want to invest time and resources of the project but want to harm the community. So if this barrier is low more scammers/spammers can participate which will lead to lower quality of the whole ecosystem
  meaningful participation - this point is connected with the previous one: people who are interested in the development of Cardano and can add value to Cardano should participate
