IT'S HARD TO LEARN
You have to learn about the rule variations. Then you have to learn basic strategy for the game(s) you will be playing.
IT'S HARD TO FIND A GOOD GAME
You are likely to spend a lot more time looking for good games than playing good casino games.
IT'S HARD TO ACTUALLY COUNT CARDS IN A CASINO
After you become proficient at counting and find a decent game, you're going to have to actually do it in a casino.
THE PROFIT POTENTIAL IS VERY LOW
There is nearly a universal misperception that you can make a lot of money by counting cards. That is simply not the case.
THE BANKROLL SWINGS CAN BE BRUTAL
Big losses have an impact both financially and psychologically. Few beginning counters appreciate how bad it can get.
YOU WILL GET CAUGHT
I know counters will get caught because I teach catching counters to casino management. It's easy to spot counters if you know what to look for.
AFTER YOU'RE CAUGHT, YOUR PICTURE WILL BE DISTRIBUTED
The casino will most likely have several high resolution images of your face ready to distribute.
