I see NFTs for peace, to raise funds for those affected by the war, by the war in Ukraine only?
The answer is simple: people and trust.
When raising money for a cause, you need to be able to assure donors that the funds will be used in accordance with your statement.
I have direct contact with people I trust in Ukraine, but not in other countries where there are conflicts
From my place, what makes me see this? [...] because it is Russia, historical opponent of the US imperialism.
In no case is our project against something or in favor of any party in the Ukrainian war, but for peace. Simple as that
On the other hand, I can admit that I am more affected by the Ukrainian war than by the others because it occurs in a country that is close to mine, where people I know live.
But that does not mean that I am insensitive to what is happening elsewhere. Nor does it mean that I never acted to support the victims of other conflicts. I regularly do, but in a less public and visible way. I rely on other organizations that have resources on-site and in which I can put my trust.
Hopefuly I answered your questions.

Apart from the fact that an NFT cannot be modified, I don't see the point of changing them to make them more generic if the funds raised are not to be donated to a trusted cause otherwise it would just be a scam to enrich ourselves. As we (the Hivebuzz team) don't actually trust any individuals or organizations working to end all wars, this will remain as is.
