as you said all these defi projects look like hype so I think you should be careful when you want to participate in a defi project, don't let you use all your assets to enter there because the potential for losses is very high, you better participate in defi projects which is well established and has clear development.
You right, nowadays the hype really really influences a person's mind to participate in such a project and from some of the existing game project hype it finally suffers a setback and those who invest in the project just because of the hype in the end have to suffer big losses.
It's not wrong to invest in projects that are currently in a hype trend, but it's usually those who invest at the beginning of the hype who gain big profits and while those who are a little late in investing in the project will have a greater risk of loss when the project hype is slow started to disappear.
But if the project is legit then all first and last investors will surely get what they have anticipated but a project will surely become a scam when the developer would just run without anything to say, in this kind of field ones should always research first before taking their hand on their investment or trusting a project,
sometimes hype is really good to make a project more successful and I think developers surely want that to happen, but it will surely depend on the developers that you are trusting.
