An oriental image of a missionary. On October 6, 2022, Matteo Ricci (1552-1610) was born 470 years ago. An Italian missionary. A mathematician, cartographer and sinologist, he is better known in China as "Matteo Ricci". But what I am more concerned about is that the clothing pattern on this image is so familiar. Bitcoin, Bitcoinism, is also a religion, and there are also a group of missionaries who preach everywhere and spread digital civilization.
