How do you tame a goldfinch?

As a professional practitioner in the field of cryptocurrency and finance, I'm typically dealing with matters of digital assets, investments, and market trends. However, if I were to approach the question of "How do you tame a goldfinch?" with the same level of curiosity and precision, I would pose it in a manner that explores the nature of the bird and the techniques involved in establishing a bond. Might I inquire, how does one cultivate a relationship with a goldfinch such that it can be said to be "tamed"? Is it through gradual exposure, regular feeding, or a combination of both? What are the key behaviors to observe in the bird that indicate it is beginning to trust its human caretaker? Are there specific tools or environments that facilitate this taming process? And finally, what is the most important aspect of the taming journey—patience, consistency, or some other quality?
