Which top 30 coinmarketcap rankings are most undervalued and why do you think this?
As per my knowledge , the new coins such as Celestia still undervalued. its a unique project. Do your own research before investing
But you are not reading the thread completely ?
OP is asking about RANK 30 in coinmarketcapitalization in which Celestia fall at rank 55 now
https://coinmarketcap.com/currencies/celestia/but indeed that Celestia is undervalue because have been watching this one for some time now.
but for me it is DAI that Undervalue
https://coinmarketcap.com/currencies/multi-collateral-dai/Bitcoin. Seriously some might think it's too late but people are still early.
Like you I still believe that bitcoin is still undervalued but I believe this thread is created and asked in altcoins meaning op is asking for altcoins.
