All exceptionally rare items have small markets as the wealth distribution of the world is pretty much disastrous. But think about it this way: if you have 50M+ USD liquid wealth you're already in the territory of diversification into fine art/historical items.

For someone with that money and appreciation of cryptocurrency, this item is basically a no brainer. You can be 100% sure that in 5-10-15-20-30-50... years, no matter what happens to Bitcoin/crypto, this item will keep appreciating and its rarity and value will only increase.

In comparison, other historically important newpapers (for example the newspapers which had assassinations of presidents on their front pages are at 20M+ USD currently for even the damaged examples).

Yes, and it is considered cheap, considering the 1M+ USD the last good example was sold for. This item is exceptionally rare.
