The reason for this comparison is to let us know that, wherein Doge can attain whatever price due or hype and fomo, it will most likely not sustain that price on the long term, so yes it has the possibility of getting to $1 if that hype remains. Cardano being a good coin grows gradually as expected, the more the team pushes out development, the more attractive the platform gets and the more investors comes in, it might take time to reach $3 but it is also achievable.
$3 is very achievable on ADA. with their solid use case, they can go far in this market. and it is true, the development of doge vs ada is really very different. the ATH of ADA right now is $1.82, so hitting the $3 mark is very possible in the next coming months.
if we will see more projects that are being developed under their network, they can very well achieve a new ATH. since it is deemed to be a good alternative option for ETH, and if their main features in identity management and traceability will be utilised by many companies, this will be a very good push for ADA to further increase its value
