I think they'll move with Bitcoin, but i don't see them having any real use unless Elon integrates something into Twitter.
If we objectively look at the entire cryptocurrency market, we will see that most of the coins are like this. In most cases, the value of a coin is determined not even by the market, but by the professionalism of market makers who use a news hype to choose the direction of price movement.
Whales hold 80% of Memecoin, especially Memecoin which still has a low market cap, of course it's very easy to pump and dump,
just look at the Doge price in 2020, and when Elon Musk talks about Doge then the Doge pump is high,
I'm sure Elon musk has 40% or 50% supply of the doge he holds.
