Many digital artists who are not accepted by the traditional art field can enter the art market without pay much price by NFT. Investors from the encryption field and other people who are very different from the traditional collectors can skip the opaque traditional art market and collect artworks directly in the decentralized blockchain. The artist believes that NFT is a ticket and it provides a way, which is different from the galleries, auction companies, art museums, to intervene the art field for the people. Taking advantages of the fact that the field of encryption art has not been solidified, we can enter the art world with tickets and seize the opportunities.
