I think DOGE is the biggest meme coin that has ever existed in the crypto market, because DOGE is a coin that was really created for the change and development of crypto currency, where its profits can surpass even BTC, and that really is a reality where Several years ago, Doge coin holders were able to make huge profits,
if its profit, btc holder at very initial stage have bigger profits, meme coin only come along making massive increase after elon has personally been shilling for it, you can imagine the influence when there is billionaire quite literally just shilling for the coin it will have massive increase. but right now bitcoin have already have so much increase in price that majority of people resort to invest in other coin including meme coin.
Doge is still the biggest, is among the few 'true,' decentralized altcoins and pioneered several things, few people know that Doge was the second blockchain to support a tokenization platform, back in 2014
Of course, Shiba has grown, has good qualities and is the main contender
i honestly don't remember doge support tokenization though since its just ordinary blockchain and until now there's no way to create token under the platform since it doesn't implement smart contract functionality.
but its indeed among the first coin to be released i think if im not mistaken and also earliest meme coin ever.
