In my view dogecoins was just hitted it's lucky strike when it got shouted by elon musk and when the crypto hype started to spreading around the world, there are a lot of people who knows the dogecoins first before they know bitcoin more over the crypto space itself.
So dogecoin is a memecoins which blessed with it's luck to create a massive pump to the crypto market and affected so big caused of many people joined the market
But on the contrary, I feel that I was familiar with Bitcoin before getting to know Dogecoin thoroughly in the crypto space, so what I am still monitoring and seeing at the moment is Bitcoin, then new altcoins including Dogecoin which is a meme coin but is still very good to own. in the short term.
I think he was trying to say that we should thank dogecoin because dogecoin make the crypto space more popular. It is hard to deny it but its true because doge coin started the meme coin hype and this leads for many newbies to enter because of the will to earn easy money and after they fail they will then explore for more possibilities and found that there more in crypto.
We that are much early to get involved in crypto, it was the bitcoin that we discovered first because there are no other hypes before but btc is only the known coin because it has the highest value among other cryptos. Anyway, I cant say doge is a failure because of its value but it should not be considered for long term investment.
