Query: Predicting the Bubble of Non-Fungible Tokens (NFTs): An Empirical
  Investigation   Our study empirically predicts the bubble of Non-Fungible Tokens (NFTs):
transferrable and unique digital assets on public blockchains. This subject is
important because, despite their strong market growth in 2021, NFTs have not
been studied in terms of bubble prediction. To achieve the purpose, we applied
Logarithmic Periodic Power Law (LPPL) model to the time-series price data of
major NFT projects, retrieved from nonfungible.com. Results implied that, as of
December 20, 2021, (i) NFTs in general are in a small bubble (predicting price
decline), (ii) Decentraland project is in a medium bubble (predicting price
decline), and (iii) Ethereum Name Service and ArtBlocks projects are in a small
negative bubble (predicting price increase). Future works are to refine the
prediction by considering heterogeneity of NFTs, comparing other methods, and
using more enriched data.
