OK, let me try to help. You don't "buy" masternodes, a masternode is a Dash full node that besides basic services like propagating messages and securing the network also provide special services like mixing and securing instant transactions, all coins need full nodes but most coins only use them for the basic functions inherited from Bitcoin. In the case of Dash there is added value functionality that is provided by the full nodes. The 1000DASH is a collateral that establishes a bond of trust between the masternode and the network and prevents Sybil attacks, because people can't just create a bunch of full nodes for free to attack the network, this makes the masternode network really secure. In this sense the 1000DASH are a collateral, you don't "buy" a masternode as you never give up control of your 1000DASH to anyone you always retain control of your coins and your are free to sell them whenever you like. Obviously if you sell them your node stops running and you stop getting paid as you are no longer providing a service.
我来试着回答你一些关于主节点的问题。你并不是“购买”主节点。它是达世币特有的多功能节点，不但拥有传送信息，增强网络安全的基本功能，同时还具有混淆币和保护即时支付交易等特有的服务功能。所有币都会经过主节点，而大部分币的交易只会用到它的基础功能，这点传承了比特币的传统。但达世币赋予了主节点更多的价值功能。以1000个达世币作为担保，从而建立网络与主节点之间的联系是为了防止攻击，这样就不会有人无限制的架设主节点来攻击网络了，这使得达世币网络更加的安全。这里的1000个达世币只是作为担保，你并不是花费1000个币来买主节点，因为你还拥有对1000个币的控制权，随时都可以卖掉这些币。当然了，一旦你卖掉它们，主节点就会自动停止，由于主节点不再为网络提供服务，返利也将会随之停止。
For providing different services, Masternodes operators get paid a portion of the block rewards,exactly like miners, this portion is divided between all existing masternodes, exactly like miners too, so the more masternodes there are the less money they get for providing these services. This creates a natural market dynamic that depends on market sentiment and investor confidence, if investors perceive less risk they are willing to take a smaller reward and thus the masternode count continues to rise. When the market feels the rewards are too little it may correct, so on and so forth. It is a self correcting system. The Dash full node network is serving its purpose really well and more services will be added on top of the already existing ones.
通过主节点提供的各种服务，主节点持有者会从每个区块中得到一定奖励，如同矿工（矿机）一样，当然奖励也会被所有主节点平分，仍然和矿机原理相同。从而主节点数量越多，每个主节点所得到的返利就越少。它的数量会在市场气氛以及投资者信心之间达到一种动态平衡。也就是说投资者认为风险小，有意架设节点获利时，主节点数量就会有一定的上涨，而当每一个主节点返利降低时，又会有投资者撤销节点来进行币的买卖等等。总的来说这是一个可自我调节的动态平衡系统。达世币的主节点网络非常优秀，在现有的功能之上，更多的服务将被添加进来，服务项目将被不断扩充。
You can easily calculate your payments in Dash from running a masternode, just like you can calculate your payments from mining. Right now a Dash full node operator gets around 0.5 DASH per day, if you think of that based on the exchage rate today that comes out to be like 1.50 USD per day that is around 550 USD year, while you hold around 3000 USD worth of Dash as collateral for your full node to run and are free to sell that at any time, is not bad. But in reality just like with mining people are not running master nodes for the current exchange rate, you run masternodes to accumulate Dash now, so that you can potentially realize gains in the future at much better exchange rates or just directly spend Dash for goods and services. So just like mining people take a risk now as they see a lot of upside potential.
你可以很容易通过在线主节点数量计算出你的主节点返利回报，就如同你可以通过算力多少来计算矿机的盈利一样。现在达世币主节点持有者一天大概能够得到0.5达世币的返利，由现在的汇率来说的话相当于1.5美元每天，550美元每年。想想看用价值3000美元的达世币作为架设主节点的担保，随时能够卖掉，又能得到如此的回报，挺划算的，不是么？以目前的汇率去架设主节点，计算返利，更多的是为了以后汇率提高后的盈利，或直接使用达世币进行商品买卖，或其他服务。也正如同矿工们看到了它未来的发展才承担现在的风险一样。
About a future where running a masternode requires a larger amount in FIAT terms as collateral due to price appreciation, I think that is a future everyone is hoping for. The collateral requirement could always be lowered when that time comes or people can take advantage of shared masternoding which is already very popular and there are several services available for that, just like pool mining. I hope this clarifies a little.
至于未来是否有天购买主节点会花费更多的问题，我想这也是未来所有人都期待的。如果周围环境符合，要求架设主节点的条件可能会降低；甚至有天人们可以通过共同架设主节点来获得返利，其实现在已经有这样服务了，如同矿池一样。我希望通过以上这些做个小说明。
