Well, we heard many baby named attached to memecoins, though this meme coin named as, billion dollar baby coins still reflect in memory of other memes coins with "baby" attached to the most successful memes coins like badydogecoin, babybonk etc. I just hope that the billion dollar baby coins (BDBE) meme coin will showcase a good project the will benefit participants.
Concerning Btc dominance, i doubt if any meme coin out there will be able to challenge the Btc market dominance, there are altcoins thought to break the dominance factor but we're not, rather they are all being dominated on the daily basis. In facts, memes has no such strength in my opinion, but let watch how your plans goes in near future.
