thanks for sharing. There are great maths behind ethereum 2.0. The tables he has shown are really simple and easy to understand. "The user must first acquire 32 ETH.."
Yes, it is determined. 32 Eth is current spec.
You can talk a lot about the project, but what they did was 32 and not 64 or 1000 for the minimum value, the devs and vitalik shows that the project is not for quick money but for decentralization and people. An ordinary person can easily buy 32 eth and become part of the platform. Well done eth devcore!
