Down voting people playing devils advocate while presenting legitimate points of argument doesn’t make them wrong.
It's good to learn the cons of things, especially if you are invested in them. People present legitimate opinions on here quite often that don't align with the "all hail Crypto" ideology and are ignored or downvoted for it.
Someone presenting point as to why a certain coin could fail or lacks scalability while everyone chants around it isn't a bad thing. It's good. Emotional investing in crypto is so easy to do and these people provide us a chance to ground ourselves and maybe double down on our on research.
Simply trying to ignore these people or downvote them into oblivion isn't healthy for the community. Otherwise we all end up blindly following a memecoin.
