To the country, it is a good way. But in my opinion, I think the way is to deprive their freedom, change their life model. They will become not wild in the nature. Such as the Perfect World Gold, if it does not use in the game, it will lose its use. Everything has its useful in the world, to the animals, they keep the natural balance. To the game gold, it is use for start the game.
If one day we keep our Perfect World Silver only in our pocket and do not use them, in order that we can save much. I think it is also not suitable way. If we only do by this way, we would rather put them into the game and have more chance to win back much more, instead of saving.
So sometimes we can change our way to solve some problems. I am a person who will take a careful consideration when I suffer a problem. After that I will take a best way to solve it. And it will not have some bad or the least bad to the question. Such as the Perfect World money, I know it is the safest way to save them, but why not try a better way and increase their value when you save them. It is means that you can get much more from others, you can use little of them play in the game, and then use your best skill to win much. Then you can have a lot of pw Gold than before. It seems just like the stock, you invest little, but sometimes you can get much more than before. Play games is the same meaning. Invest means that you should Buy Perfect World Gold for stock. Then use them to win others game gold.
So do not take a bad way when you make a decision. Take a careful consideration when you have many choices. Such as you are making a decision that will make you lose much money, if you choose the wrong way, you will lose something, maybe some money, maybe some cheap Perfect World Gold which are your lovers.
