I read this in trading: “- 60% of all DOT is currently staked by only ~7000 delegators (nominators), while cardano has 68% staked by 133.000 decelerators. Polkadots has a lot of whales with a lot of voting power that also could dump at any time. - Polkadot has a 10% inflation, meaning if you chose not to stake your DOT for one month your DOT would loose its value by 0.83%, which is insane when you have to lock your DOT for 28 days to stake. - When applying for funding from the Polkadot treasury you have to put down 5% of the amount you are applying for (in Cardano you don't need to put down anything), if the proposal gets rejected you loose the 5%. There is no other funding agency that I know of that takes your money if your proposal gets rejected, and this will be a threshold for most developers. The proposal voting is done by a committee of only 13 members, while in Cardano everyone that has ADA can vote on the proposals.”
