Whats the minimum amount needed to invest in order to join the sale?

I believe it is 25 ETH minimum to participate.Kinda high for me unfortunately Sad

Most likely that is the minimum for presale. What is the situation for the main sale?

25 ETH is high even for presale.Maybe its for private sale,that phase tends to have higher req

Ye 25 ETH is alot,im sure its for private sale round.

Who ever has that I'm sure it will be a good investment.

Yes,its most beneficial to be early investor,you get biggest bonus
