In last one week, coins like pepe rose by 400% or more. There were other meme coins like dogecoin and shiba inu also growing fast.
Well, they got hyped because of Bitcoin's sudden rise in the past few weeks. I mean in times when Bitcoin goes up in price, so do altcoins, but not instantly. Don't look at meme coins too high. You might lose your money investing in it.

Lot of bitcoin users would now feel tempted to move their funds to these meme coins for higher profit. At such, do you think that any meme coin has the capacity to challenge bitcoin dominance ?
Eh? Where did you get this idea? Do you have numbers to back it up? I'm a Bitcoin holder, but I'm not even thinking of selling it just to buy those meme coins especially now that it went up in price already. Any meme coin can challenge Bitcoin's dominance? Are you kidding me? Are you a meme coin maximalist think about that. Ok, I'll just assume that you're a newbie in investing, and meme coins are the first thing that you saw in Coingecko or Coinmarketcap hence, you are posting threads like this.

Not even Ethereum can challenge Bitcoin's dominance so why think about it with meme coins?
If I were you, I would not look at meme coins that high because TBH, they are very risky to invest in. Maybe those meme coins at the top 100 are considerable, but those below? You can invest still though, but be careful, and most meme coins don't have any use case at all so for me, they are considered useless.
