I've been following the project for a week, I'm very happy to be a part of it. I'm going to invest 30 ETH soon

In my opinion, this is a very big contribution, both from one person. You're cool, buddy
Are you kidding?

30 ETH is a common investment, I believe. Really great contributions start with 100 ETH
What are you talking about, I only have 5 eth ... I think that even a small contribution is very important for such projects

This is important, of course. But your 5 ETHs are not comparable to thousands of ETHs... And it will bring more benefits to the project than you. You're only here to make money, are not you?
