I don't think that he'll stop supporting it. But he'll continue to troll and play with it through Twitter account. He's loving the attention that's given to him and that's why we might never see him stop doing so. He's earning from it as well and that's why he understands that if he ever need some few chunks of profit like a couple of hundred thousands, he'll just need to talk about it and just do one tweet over it and then the increase will be visible so quick.
What actually makes you think that a billionaire who is the richest person in the world would need a meme coin to give him profits? He has enough businesses to earn him enough money without having to do that, so even if he plays around with it, it doesn't really mean that he is profiting from that. That's what I think.
thats always the thing with investing in new projects, too much saturated with scams but some of them are indeed high quality like the ones coming out from reputable platform.
therefore you need to choose diligently which one is promising, otherwise it will be the same as investing in shit coin that should be avoided because of scammy.
A person will always need to at least do some research from their own end before they get into a financial market like the cryptocurrency market. So, whether they are investing in new or old projects, evaluation is a requirement. But it's true that when a market gets too saturated, there will always be fake entities among the crowd and only proper research and analysis can make someone safe from them.
