I want to take part in NFT presale, need an advice

Hi! I came across this new NFT program. They say they sell their NFTs to fund better and faster space exploration so mankind has a plan B for our survival. So basically it’s a charity. And I think it's a worthy goal. But I also thought if I get an NFT with that I might even sell it later. Which means I could get my contribution back or even get a profit. I don’t know who I can sell it to later and how all that would work, but all that looks interesting.

The NFT campaign is called Patronize a Star. They have a community r/PatronizeAStar. Their founder did an intensive AMA session recently on reddit and it seemed to have aroused great interest in the campaign.

They had an airdrop campaign recently. Per Rarible and Opensea NFT markets they already sold some NFTs for 0.4 Eth. But currently they have a presale ongoing with 0.02 Eth per NFT for the next 36 members.

I would like to participate in their presale, they say it is the lowest price ever. It will be happening for the next 3 days. Do you think it's worth it?
