Of course not. Memecoins are speculative altcoins, so it's natural few of them deliver high positive volatility on short run, especially taking into consideration the moment of crypto market we are currently living. At same time, it doesn't mean they have potential to overcome Bitcoin dominance.
While Bitcoin keeps rising on long run, always achieving new ATHs each new cycle, these memecoins hypes tend to last only for a single cycle. Once it's over, it's over forever, so what speculators do is to find a new memecoin to boost on the next bull run. And they keep doing this in a continuous process similar to Ponzi schemes, where early investors make money, while late investors lose.
The fact many investors' eyes shine with greediness for such massive increasements in price like 400%, lead these people into believing random altcoins can overcome Bitcoin inside crypto market, although there isn't any solid bases for that happening.
In all honesty, I don't think any meme coin or token will surpass the popularity or dominance of bitcoin. Meme projects are mostly driven by hype. Think of their actual use case or foundation and you will understand why most of them are short-lived. Because let us admit the fact that most of them are created for the enrichment of their own devs, nothing more.
Lot of bitcoin users would now feel tempted to move their funds to these meme coins for higher profit.
Do you have any data to back this statement of yours? If no, then you shouldn't make things up on your own because I'm pretty sure that a sane investor would never be tempted to move their funds from Bitcoin to a meme coin just because of the short-term profits they can provide because they are not as strong as Bitcoin both fundamentally and technically. If someone thinks this way, they simply have no idea about Bitcoin and the market because someone with enough knowledge would know that Bitcoin is a much better investment despite the fact that some other coins including meme coins might be providing higher profits in the short run.
I don't think anyone can get the statistics on this particular subject. Maybe, you can feel that a lot of people are into meme because they are loud in social media channels. But we can never be sure also about the figures of btc holders. So yeah, we can't conclude on this matter.
