Hello @crypto.piotr
High APY projects can be a double-edged sword, that is very clear.
They mean a big challenge for the whole team behind the project.

Just as you say, generating a big profit margin the first days can be attractive for anyone, but it can bring investors who only think about short term profit and affect a lot the project in question, it's a great truth.

On the other hand, and it is a viable option, is that the benefits are not only focused on the short term, that's when I say it is a challenge for the team behind the project. Because they would have to look for ways (products, tools, utilities,) so that people do not want to leave with their money and profits, that they see that beyond a few months there is something more, something that makes them want to keep their money in the project for years even.
