# Proof of investment

Ownership of a GM NFT with a **level above Earth** should be sufficient to prove personhood. The capital outlay to achieve these NFTs should be enough to discourage their usage in Sybil attacks and prove the investment deployed for better action to VeBetter.

{% hint style="warning" %}
The GM ownership is snapshotted at the beginning of each round to prevent potential attacks.
{% endhint %}
