近年比特币相关重大安全事件 vs 比特币系统本身的安全性有很多重大的比特币相关安全事件，但是基本上都不是因为比特币系统不够安全。 比特币是去中心化的，太多的悲剧都是因为人又依赖于中心化了-把自己的信任交给了中心化的交易所。以下内容来自刚刚和chatGPT的对话。

can you list out the top 5 safety incidents related to bitcoin in the past 10 years?
Sure, here are some of the top 5 safety incidents related to Bitcoin in the past 10 years:
1. Mt. Gox Hack: In 2014, the largest Bitcoin exchange at the time, Mt. Gox, suffered a security breach that resulted in the loss of 850,000 bitcoins, worth around $450 million at the time. This incident raised concerns about the security of Bitcoin exchanges and the safety of funds stored on them.
2. Bitfinex Hack: In 2016, the Bitfinex exchange was hacked and lost 120,000 bitcoins, worth around $72 million at the time. This incident led to a decline in the price of Bitcoin and further highlighted the need for better security measures in the cryptocurrency space.
3. Cryptocurrency Exchange Scams: Over the years, there have been numerous instances of cryptocurrency exchanges disappearing with customers' funds. In some cases, these have been outright scams, while in others, the exchanges have failed due to poor management or a lack of security measures.
4. Ransomware Attacks: In recent years, ransomware attacks have become increasingly common, with hackers demanding payment in Bitcoin. While the use of Bitcoin as a payment method can offer anonymity to the attackers, it can also make it difficult for victims to recover their funds.
5. Phishing Scams: Phishing scams, where hackers trick individuals into giving up their private keys or seed phrases, are a common threat in the cryptocurrency space. This type of attack can result in the loss of funds, and it highlights the importance of using secure methods for storing and managing cryptocurrencies.
It's important to keep in mind that the cryptocurrency space is constantly evolving, and new threats and security incidents are likely to arise in the future. It's always recommended to stay informed about the latest developments and to take appropriate security measures when using cryptocurrencies.

are these incidents due to the bitcoin system itself?
Not necessarily. Most of these incidents are not due to flaws in the Bitcoin system itself, but rather to the security practices of individuals, exchanges, or other third-party services that store and manage Bitcoin.
For example, in the case of the Mt. Gox and Bitfinex hacks, the security breaches were a result of vulnerabilities in the exchanges' systems, not in the Bitcoin network itself. Similarly, scams and phishing attacks often rely on tricking individuals into giving up their private information, rather than exploiting weaknesses in the Bitcoin system.
That being said, the decentralized nature of the Bitcoin network does introduce some unique security challenges, such as the need for individuals to securely store their own private keys and the potential for double-spend attacks. However, these challenges are largely manageable with appropriate security measures and education.
In conclusion, while the incidents mentioned above have highlighted the need for improved security in the cryptocurrency space, they are not necessarily a reflection of flaws in the Bitcoin system itself.

比特币挖矿的电力According to the Cambridge Bitcoin Electricity Consumption Index (CBECI), the estimated annual electricity consumption of the Bitcoin network is around 114.67 terawatt-hours (TWh) as of September 2021. This represents approximately 0.5% of the global electricity consumption.

中本聪在2010的看法如下，那时候比特币挖矿用的电力还很少，用的是一般的电脑，还没有开始用GPU挖矿， 更不用说矿场和矿池。https://bitcointalk.org/index.php?topic=721.msg8114#msg8114

It's the same situation as gold and gold mining. The marginal cost of gold mining tends to stay near the price of gold. Gold mining is a waste, but that waste is far less than the utility of having gold available as a medium of exchange.

I think the case will be the same for Bitcoin. The utility of the exchanges made possible by Bitcoin will far exceed the cost of electricity used. Therefore, not having Bitcoin would be the net waste. 　[本文发送自华新手机Wap版] [ajie65 (3-12 13:37, Long ago)] [ 传统版 | sForum ][登录后回复]31楼

BTC会不会变成另外一个郁金香泡沫？摘自2012-9-12吴忌寒的"BTC会不会变成另外一个郁金香泡沫？" 来源：http://btc.mom/5202/
...
比特币从31美元跌破2美元，这样的熊市不可谓不惨烈，但之后他的用户在持续增加，汇率也强劲反弹到现在15美元上方，这个反弹过程在最后已经形成了一个泡沫，而它的破裂也迅速将价格打到了7.5美元。现在价格又重新稳定到了11美元。未来比特币的汇率运动将持续表现为泡沫的形成和破裂。很遗憾，人类群体的思维方式并不能理性计算出一个合理汇率，以一种匀速上涨的方式反映比特币经济体的扩张，只能以这样的过度上涨+修复的形态来不断试探和寻找均衡点。

(引用 集团贵宾客户:还是太贪心了没等到就起飞了)拉长时间线来看现在还算是底部区域。　
　
所有的人都是贪心的，人性，。避免错过底部的一个办法分批买入。想要全部资金都买到绝对底部，几无可能。一个缩水90%的熊市底部还要在缩水80%的熊市底部再往下跌50%。 要把准一个熊市是要缩水70%，80%还是90%，太难了。
　
从更长的时间线看，btc一定会再创新高。再创新高的时候，*任何*一个时段买进的比特币都不会被辜负。

重回3万刀今天比特币终于在9个月后重回3万刀。恭喜各位币友~
　
中间没有卖出操作。3月10日还趁着市场恐慌把前后几个月定投的额度买了eth屯下来。
　
btc回到3万刀，这一轮纸面盈利50%。
　
安安心心的屯着,　
　
希望大家都没有浪费这个大熊市和大回调, 。

这一个周期的叙事上一个周期defi，gamefi，NFT，机构（灰度，特斯拉，microstrategy，美图等）入场。 这个周期有什么期待呢？defi, gamefi, LSD, NFT多是一众非比特币应用的扩大。比特币能有什么叙事呢？我妄言一个中型以上的国家动用国家力量挖矿，屯比特币，或者采用比特币作为该国的法定货币/法定货币系统的一部分。伊朗，中东某国，或者俄罗斯？猜猜那时候比特币的价格能到哪里。。。妄言而已，勿拍。 [ajie65 (4-15 21:20, Long ago)] [ 传统版 | sForum ][登录后回复]37楼

MicroStrategy这家公司有点意思，MicroStrategy Incorporated is an American company that provides business intelligence (BI), mobile software, and cloud-based services. 不务正业，斥资41.7亿美元，以29803美元的均价买入14万个比特币。看着均价比我这一轮的高这么多，又多了那么一丝丝的安全感，。

货币的非国家化理论 - 哈耶克https://wiki.mbalib.com/wiki/%E8%B4%A7%E5%B8%81%E9%9D%9E%E5%9B%BD%E5%AE%B6%E5%8C%96%E7%90%86%E8%AE%BA

货币非国家化理论概述
　　哈耶克从彻底的经济自由主义出发，认为竞争是市场机制发挥作用的关键。而政府对于货币发行权的垄断对经济的均衡造成了破坏，他通过研究指出并论证竞争性货币制度的可行性和优越性。哈耶克宣称：货币非国家化是货币发行制度改革的根本方向，由私营银行发行竞争性的货币（即自由货币）来取代国家发行垄断性的货币是理想的货币发行制度。因此，他的这一主张称之为“货币非国家化”或“自由货币说”。

　　哈耶克的这一学说与他早年提出的中立货币说是遥相呼应的。中立货币说的核心思想是稳定货币供应量，保持货币的中立性。但这种仅仅停留在理论上的分析，只提供了货币政策实际效果的一个判断标准，而很难付诸于实施，缺乏现实应用意义。面对20世纪50年代以来世界各国通货膨胀的不断发生和加剧，哈耶克从经济自由主义出发，在进一步研究的基础上提出了货币非国家化的设想。认为货币失去中立性，以致破坏经济的根源，在于政府对货币发行权的垄断，必须打破垄断，由私有银行发行竞争性货币来代替国家货币，建立货币发行的内约束机制，才能有效地限制货币供应量，维持币值和市场经济的稳定，消除失业和通货膨胀。
