When the iPhone 4 came out, I was just about to change my phone. After comparing them every day, I suddenly didn’t want any Sony or Dopod anymore. I became one of the first people in the county to buy one, and I persuaded many people to join the trap.

At that time, stocks, cryptocurrency trading, and investment were beyond my sight, so I couldn’t know that I should buy stocks instead of mobile phones, let alone Bitcoin.

The world is so big, and the differences caused by information gaps are greater than the differences between people and dogs.
