well #1 would be Charles Hoskinson and his history...
but more meaningful opposition would be in why use a DPoS network now that we can have PoS networks without the delegation?
if you value decentralisation and think it has a future why would you go for a DPoS network that can so far just send tokens, there are better dpos networks like cosmos or polkadot, and ethereum is moving to pos. What is cardano actually (still attempting) to solve that hasnt already been solved by polkadot/cosmos?
Why use haskell as the contract language? do you think in the limited pool of blockchain developers there are many people are wanting to write haskell? and that they are going to port all the existing tokens/defi/contracts made over the past few years to a haskell+utxo model? who is expected to build on this. in 15 years of dev work ive met a handful of haskell devs, they are all in academia and dont make production software.
And alongside that, and why i refer to it being pumped, is that it is getting so much publicity but barely being used. i just looked at the block explorer and in the past ten blocks three are empty and the rest have a top of 10 transactions being processed.
Where are the supposed network effects driving it? shouldnt the blockspace be in demand? especially with the recent price surge, if the price is going up but it has empty blocks surely that is a bad sign?
What do you see in Cardano that makes it a poor candidate for a future blockchain? Governance? Functionality? Algorithms? Investment?
