What is coin checking?
Could you please elaborate on the concept of 'coin checking' in the world of cryptocurrency? I'm curious to understand what it entails, how it's done, and why it's considered an important practice among investors and traders in this domain. Is it a way to verify the authenticity or value of a digital coin, or does it serve a different purpose altogether? Additionally, what are the potential risks or considerations one should be aware of when engaging in coin checking?
