Sotheby's sold a 90cm canvas for one of Banksy's famous works, "Love is in the air," for $ 12.9 million. At 1m or less, this price is already one of the highest prices among existing artists, and I feel that this movement has finally reached this point. Banksy has risen sharply, especially in the last 1-2 years.

Moreover, this auction is so-called "Crypto Accepted", that is, "you can pay with virtual currency". It's probably the time to buy Banksy and Picasso and pay with Ethereum.
