No staking system is perfect. Some (Martingale et al.) are not even close. However, Kelly Criterion is proven to be the best way to grow your wealth. John L. Kelly was a colleague of the inventor of information theory, Claude Shannon. Kelly used information theory to show the optimal way to grow a bankroll.
The Kelly Criterion formula tells the trader the optimal bankroll percentage to risk. Percentage stakes is superior to level stakes but choose to high or too low a percentage and you will not profit as much from a winning system as you can with Kelly.
Here is a by no means complete list of Kelly Criterion citations, starting with Kelly's seminal work.
