So far we have not seen memecoin interact with other memecoins' rises. For example, since Doge's rise began, it has been moving alone without significantly affecting the rest of the cryptocurrencies. $TRUMP has risen without us seeing a positive impact on Doge, PEPE, BONK, and others, any positive interaction with them.
The popular meme coin like Dogecoin do not drive the market prices of other meme coins, it is evidence that Bitcoin drives the entire crypto market, and the Bitcoin price pump/dumps affect the market.
Trump coin experienced a severe dumps with massive losses that lead to many investors lost of confidence on the meme space, and i think that the developers where behind the dumps.
In addition, other popular meme coins that has live up the expectation of the crypto community are Dogecoin, Shibainu,Pepe, bonk, floki tec.
For me, I will not buy Trump coin, I would rather buy Pepe, Floki, bonk, and other top meme coins that are in the top 5 rank in the market. Although, for newbies, they should not try to do trading activity here, because the risk is high if they do it in reality.
Meme coins only become profitable when you are able to buy it at a low price then suddenly it pumps high, that's when you are really profitable,
but if you are wrong about meme coins, your capital will surely burn there, so it's still a good idea at all times.
