Going through the life history of Mike Tyson, he's a man of wealth. During the year 1985 itself he had a worth of 423 million which in today's valuation is very big. When wealth came, automatically his life style changed and started to spend on unwanted things. He grew two white tigers as pets and spend millions to have his exercise equipments and bathtub on gold. So, he's a man of money and money isn't a big thing for him. He agreed for some reason and now he realised and has setback stating he won't fight which is really good decision.
You are right in what you say, what happens is that Tyson in his boxing time was so successful and famous that he gave himself those luxuries, at one point it was said that he had fallen into ruin, but naturally he is a person who lives very well In fact, in the movies that he appears his appearances are very good and yes, he showed off his tremendous house, the style of his tiger and everything in the movie "What happened yesterday" and also in the IP master movie, which is from Kung Fu , his participation was excellent, also with that tattoo on his face it makes him look even more reckless.
