只要有某种形式的博彩投注系统，你就拥有更多赚钱的机会。利用这些系统的显示方式来改变你的赌注的大小，这样做，相当于用现金填补你的口袋。不幸的是，多年来，许多投注者发现，这些系统有时候不工作或者向他们提供可能让他们赔钱的陷阱。
改变你赌注大小的主要问题在于，它会扰乱你的现金流动和提高资金的收支平衡点，你下的注可能要超过你能赚取利润。意思是说：假设你在五场比赛中下赌注，每场比赛赌50美元，共250元。现在根据你的所谓的永不失败的系统，为避免连败你应该减少您的投注。所以，你降低你的赌注，50美元下调至25美元。你打赌五场比赛共花费125元。即使你赢了所有这些打赌，你收获的利润仍然会损失125 美元。通过减少您的赌注，增加下注对象，你也许能收获更多利润。当你处于不利的地位时，博彩投注系统很难帮对自己达到收支平衡或赚钱。
以打赌赚取利润，并有效地管理你的钱，最好的办法是下注。您下注的资金需要坚持一个百分比。如果您投注的成功率达56％，你可以获得一个很好的利润收入。你需要记住一件事，你赢了，您的资金就按照一定的百分比增加了。一年之后，您的资金会比前一年上涨5%。
为了保持一个稳定的平面上的利润，你应该重新审视您的资金，定期调整下注的百分比大小。还有一件事情需要记住，如果不把您的投注向下调整，当你发现你的资金有所下降后，一个坏的资金运行就在前面等待着你。

Money Management in Sports Gambling
For as long as there has been some form of betting there have been betting systems that are supposed to give you the edge you need to make more money. Many of these systems show you ways to vary the sizes of your bets and, in doing so, fill your pockets with cash. Unfortunately, as many bettors have found out over the years, these systems don’t work and the false hope they provide can make them money-losing traps.
The main problem with changing the size of your bets over and over is that it disrupts your cash flow and raises the point of breaking even that you must hit and exceed to make a profit. Here’s what that means: Say you’re betting $50 per game and you’ve just bet on five games for a total of $250. You go on a bad losing steak and pick the wrong team on all five games putting you $250 in the hole. Now according to your so-called never-fail system, during a losing streak you should decrease your bets. So you lower your bets 50 percent down to $25 a game. You bet on five more games for a total of $125. Even if you win all five of those games you will still be down $125. By decreasing your bet you have increased the number of games you must win to get back to even. You’re putting yourself at a disadvantage by making it harder on yourself to break even or make money.
The best way to bet to make a profit and manage your money effectively is to wager a percentage of your bankroll and stick to that percentage. If you can hit the magic number of a 56 percent success rate in your betting picks, you can turn this small percentage into a nice profit. One thing to remember though, as you win and your bankroll increases the percentage of your bankroll also increases. After a year of winning, five percent of your bankroll has risen from what it was a year ago.
To keep your profits on a steady plane, you should re-examine the size of your bankroll on a regular basis and adjust your percentage betting accordingly. One thing to remember though, do not adjust your betting downward if you notice your bankroll has decreased after a bad run. As we said earlier, by decreasing the size of your bet you are making it harder on yourself to get back to even. Ride out these rough patches and your bankroll should recover when you start picking winners again.
