There was a money fan who always wanted to double his money. One day he met an old man on a bridge. The old man said to him: "As long as you walk across this bridge and come back, your money will be doubled, but As a reward, you will give me 32 copper coins for every round trip." The money fan did the math and agreed. He walked across the bridge and came back, and the money on his body was doubled. He happily gave the old man 32 copper coins. After walking the fifth back and forth in this way, the last 32 copper plates on his body were given to the old man, and there was not a single copper plate left. Question: How many copper coins does the money fan have?
