I wonder you are talking about being choosy and selective when deciding to invest because not all defi projects are fake or scam because of the open ecosystem and also defi has big role to plwy in future financial sector. Yes you are right that only small percentage of projects will dominate while others will struggle or fade away.
I think what he meant is that people are crazy about DeFi projects and investing without doing some research or even understanding the project and in my opinion that's what happening nowadays and yes, only small amount of projects gonna make it long term and the rest probably fail mid-way so that's why people need to invest wisely to pick the best of the best projects.
People are really into DeFi project probably because it always give profit but its not gonna be like that forever.
Because people are for short term profit from these DeFis. Most of them are not looking about the background or foundation or capability but the hype surrounding it. As long as they can get profit, they don't care about the structure of the project. But if they get rekt, they blame that the project is fake. So the decision lies on the investor himself, not the project. They can always choose which project to support and shell out their money.
The DeFi project helps people to make money by investing in the project for the short term.
I think it's like what we did in the past when the ICO launch and make hype at the market, and people realize that if they can join the project, they will have a chance to make money.
Now, that is proven with many DeFi which can works for people to recover their losses from a long time ago slowly.
But that DeFi trend will not stay forever, there will be the end of the trend, and like usual, it will be replaced by the other new trend.
So I agree with the title, invest wisely while you can.
