I think this meme coin is affecting other altcoins but I don't think the big dump will happen but it will last for the big holders.
We will see how the reaction of the tweet will affect it once?
As usual, the tweets of Elon have been giving a positive impact on Dogecoin's price and that's why each time he tweets, expect that there's a quick increase that many of the holders are waiting for.
What's the effect that Dogecoin brings to other altcoins? I don't see any significance with its relation to it because that's quite hard to say as they have individual markets.
