Cardano got recently some attention by speculants but for fundamentals, Cardano is very weak: 

Cardano is an old coin and based on outdated models, compared to advanced coins like Ethereum 2.0, Cosmos or Avalanche. I would compare Cardano to BCH, Tron or EOS. Cardano is a very similar age. All coins failed to deliever and will be dead coins soon. Tron is already abandoned because Justin Sun failed to meet his expectations.

Because most coins, when initially started, have a vision and try to look if it works. Cardano failed to deliever it's initial vision (it started already 4 years ago and failed last bull cycle). New coins will replace it and people holding Cardano now will pay a high price.
We should avoid FOMO and instead have a look for FACTS because facts matter if a coin is succesful. Cardano is a very old coin and outdated coin here, it promised so much and delievered so little. Similar like Tron a hyped and overvalued coin.
