Whether to challenge or not, it's up to you.
After all, an underground boxing champion can often remain unbeaten for several years, even over a decade.
During this period, an underground champion will kill or disable dozens of top fighters who come to challenge, until one day he either retires or is killed by a new generation champion.
But even underground champions can't match the appearance fees of real professional champions, which generally range from one to three million.
Real professional champions sometimes have appearance fees reaching tens of millions, or even hundreds of millions of US Dollars.
For example, the century fight between Mayweather and Pacquiao.
Their combined appearance fees amounted to 280 million US Dollars.
Among them, Mayweather's appearance fee was 180 million US Dollars.
Pacquiao's was 100 million US Dollars.
Appearance fees for underground boxing matches are incomparable to those of professional bouts.
