It really depends if the whales are still backing it up and Trump will mention this meme during the course of his administration. This is one of the risks of investing in a meme that's narrative and personality-based; there is uncertainty about its future.
It could go either way; Trump will go to oblivion after he goes out of office so its potential is only good during its tenure, or it will remain in the market and be one on top of the altcoin because the community will continue to honor Trump's contribution, so this is one interesting meme to follow.
The earlier assertion is more likely to occur than the latter. What I mean is the Trump coin might have gained somw level of stability during his stay in the government but might not stand the test of time when he leaves. But if he's smart enough he can decide to strengthen and familiarize the crypto community through his coins making major multinational transactions using the Trump coin and investing a significant amount of money into the trump coin instead of Bitcoin, that might give the coin a leverage over others but the disadvantage and fear this nature of coins come with is that since it does not work on existing networks like Solana and others, it may not be able to make a long-term impact or value in the crypto market. What I'm afraid of is, the people that will end up investing their fortunes in the coin then when it later dumps, they begin to suffer from such decisions.
