NFTSに付随する価格はarbitrary意的と見なされ、上昇および下落の傾向に対応する可能性があるため、NFTが元の購入価値を長期的に維持する能力は議論の問題です。

また、NFTの大部分は、購入されたかのように無料でコピーして経験できるため、排他性を疑問視することも指摘されています。
The ability of NFTs to maintain their original purchase value in the long term is an issue for debate, since the prices attached to NFTs could be considered arbitrary and subject to rising and falling trends. 

It has also been pointed out that the majority of NFTs can be copied and experienced for free as if they had been purchased, which brings their exclusivity into question.
