1  Alternate cryptocurrencies / Altcoin Discussion / 边际思考 on: April 17, 2018, 08:31:12 AM
Marginal is the relationship between new input and new output. Linear unit input corresponds to linear unit output is not the state of real life. Since the nonlinear effect is a problem of two directions, it is either decreasing or increasing.



The decline is best understood, the matter of psychological individual correlation, mostly is degressive. Eating watermelon in the summer, eating watermelon is a linear input, the satisfaction is incremental decline. Marginal decline can be used to understand a lot of non-psychological phenomena. The leading shares in the stock are used in this concept, and the leading shares in various industries have mostly outperformed other stocks. The reason is that when most people have the need to configure the plate or hear about the plate, there is no diminishing in the leading stock. It's the same thing. By this logic, it is also possible to explain why the first monopoly market is not only because of the scale effect of monopoly. There's also a marginal effect here. It is also the case that the public is asking for attention before and after the article, at the moment when the margins are strongest. For most events or opportunities, there is a time window, and the opportunity itself has a marginal utility, with the strongest effect in the window.



One area where the marginal increase is in the media. The benefit of the media must be increasing at the margin for a period of time. The effectiveness of a single AD is limited, but the impact of successive AD bombings is beyond the current imagination. Reading and learning in many fields is also an example of increasing marginal effect, which means that the boundary value of increasing utility is reached in the current range, which leads to uncontrollable development. The marginal increment in the investment is most notable is the downward situation. Taking personal losses as an example, the downward step loss is actually a process of increasing utility, because the lower the step down, the harder it is. Bankruptcy, for example, is the most marginal damage to assets. Such losses and bankruptcies are not limited to assets.



2  Alternate cryptocurrencies / Altcoin Discussion / Cryptocurrency: an important opportunity with risk. on: April 17, 2018, 08:04:05 AM




For many investors, cryptocurrencies are not just financial assets, but promises of a better future. A process of realizing the future of the self, from a financial perspective, is a process that no longer requires a lot of time to achieve self-realization in the future. But if it only involves this profitable aspect, they will not be called revolutionaries. In fact, it is not just a process of self-enrichment of ordinary products. The emergence of cryptocurrency has completely disrupted our view of economics and finance so far. Most importantly, the technology to design cryptographic currencies is startling. The blockchain contains the real potential to bring freedom and security on the Internet to new heights.
Cryptocurrencies lack significant benchmarks.



Unfortunately, the world of cryptocurrency is now the wild west of America. The blockchain industry now lacks a strong standard. In addition, the various market participants are not very clear about the form, and the media frenzy tracking report makes the virtual currency into an inconceivable situation. Nearly a decade after the first cryptocurrency was developed, the industry is still in its infancy, according to a study by a professional company. Of course, the concept of cryptocurrency and blockchain is particularly revolutionary, but from a practical point of view, all aspects are still experimental.
3  Local / 媒体 / 投资最怕的是什么? on: April 17, 2018, 08:00:35 AM
分享两个投资界比较常用的数学公式:
控制风险的方法有很多,其中最重要的一条就是对仓位的控制。

有一个著名的公式:凯里公式,如下:


其中

f*为现有资金应进行下次投注的比例;

b为投注可得的赔率(不含本金);

p为获胜率;

q为落败率,即1 - p;

这条公式告诉我们,对于那些成功概率很高,失败了也不会损失多少的投资标的,就可以考虑下较大的赌注,而对于那些成功概率很小,一旦失败损失惨重的项目就要下比较小的赌注,这个公式就是对具体下注额的精准量化。想要对这个公式熟练运用,需要不断尝试,不断摸索,最后总结出适合自己的一套投资模型。



这个公式里面有一个难点就是,如何确定获胜率和落败率,以及赔率,这个数值如何来度量?
这就需要另外一个著名的贝叶斯公式:


公式描述:

公式中,事件Bi的概率为P(Bi),事件Bi已发生条件下事件A的概率为P(A│Bi),事件A发生条件下事件Bi的概率为P(Bi│A)。其中P(A|B)是在B发生的情况下A发生的可能性。

在贝叶斯法则中,每个名词都有约定俗成的名称:

Pr(A)是A的先验概率或边缘概率。之所以称为"先验"是因为它不考虑任何B方面的因素。

Pr(A|B)是已知B发生后A的条件概率,也由于得自B的取值而被称作A的后验概率。

Pr(B|A)是已知A发生后B的条件概率,也由于得自A的取值而被称作B的后验概率。

Pr(B)是B的先验概率或边缘概率,也作标准化常量。

我们可以依据这个公式来对投资仓位进行不断的动态调整。



比如我们发现一个投资项目,准备投资的时候,通过各种分析,不仅仅限于对团队背景,项目市场需求,社群活跃度,行业发展程度等各种因素,最后算出项目当下成功的概率,我们可以通过算出来的概率通过凯利公式来判断投资仓位。随着项目的进展,我们可以通过贝叶斯公式动态调整各种概率,然后再结合凯利公式来动态调整仓位,如此来精准量化风险,做到比较准确的规避风险和心里有数。


这就是为什么普通投资者最后打不赢专业投资者,因为很多专业投资者善于利用工具,不仅仅利用数学公式,而且会擅长使用各种强大的交易分析软件,熟悉市场的规律,能够通过工具做到理性操作,不受情绪影响。



那么普通人没有强大的工具如何战胜市场呢?
大约二十年前,曾经有一个人询问巴菲特:“你的投资体系这么简单,为什么你是全世界第二富有的人,别人不做和你一样的事情?”


巴菲特回答说:“因为没人愿意慢慢的变得富有。”


巴菲特的话和人生经历告诉我们,关注长期的人,比关注短期的人有巨大的竞争优势。


本来短期市场就很随机,涨跌平均来看可能就50%的概率,如果你玩杠杆,这种概率几乎就是50%,这就完全把市场变成了赌场,赌场的赌徒最后的下场大家都知道吧?最后赚钱的都是开赌场的人,交易所就是币市的赌场,交易所天然有让散户玩杠杆的冲动,这样交易所才会赚更多的钱,他们天然只宣传最后极少数幸运儿通过玩杠杆赚大钱的故事,而对那些爆仓的人会避而不谈,这样就会给人一种玩杠杆很容易赚大钱的假象。


赌博最怕的就是没有筹码,没有筹码就没有玩的机会了,而不断的加杠杆来玩,是最容易让自己的筹码清零的方式了,而且数字货币市场是最容易出现黑天鹅事件的地方了,一个黑天鹅就会让你爆仓,最后没得玩,如果你不加杠杆,一切都只是账面上的浮盈,而你的币并没有少,如果区块链是未来大势所趋,早晚你的账面浮亏会变成浮盈,不至于最后永远无法进场。

评论精选:(精选评论将获得大圣能量赞奖励)


我就是世界名人:没错,我是风险厌恶者。而且我还缺本金。而且我还没法专注此事。看来必须要改变了。放纵自己并不好。糟糕透了。不过看起来邻居这傻逼不但放纵还无比邪恶。可这和我有什么关系呢!确实如此。 另外我要说的是我并不懒。赚钱就是我的思想和信仰还有行动。也是我忠实的伙伴。人类是邪恶的。是丛林社会。


币小白团队:对冲规避大涨大跌的风险适合长期持有投资者,但是搬砖获利建议小散不要碰了,楼主给的办法挺好,没有一定的执行能力的话还是不要碰的好
