I also believe cardano will be on top 5 soon.
Cardano is already in the top 5 on Coinmarketcap and yesterday in January Cardano was at number 4 in the Coinmarktecap and Coingecko rankings.
This proves that Cardano is indeed very stable and good for performance issues in terms of blockchain, transactions, security, community or from a fundamental point of view.
Cardano is like the golden child of a family, if Bitcoin and Ethereum are mothers, then Cardano is the golden child of both.
