#分布式
开写我的分布式原理教程，初步想好的名字是《图解分布式系统原理》。想写这个教程，是因为重读DDIA的过程中，发现在分布式这块，有很多地方没有展开写。例如happen before关系，例如共识算法（作者一笔带过，我严重怀疑他可能不会：）。
目前先在Latex上写，后续写好了会逐章公布在网站上。

Like a stock, you can buy and hold Bitcoin as an investment. You can even now do so in special retirement accounts called Bitcoin IRAs. No matter where you choose to hold your Bitcoin, people’s philosophies on how to invest it vary: Some buy and hold long term, some buy and aim to sell after a price rally, and others bet on its price decreasing. Bitcoin’s price over time has experienced big price swings, going as low as $5,165 and as high as $28,990 in 2020 alone. “I think in some places, people might be using Bitcoin to pay for things, but the truth is that it’s an asset that looks like it’s going to be increasing in value relatively quickly for some time,” Marquez says. “So why would you sell something that’s going to be worth so much more next year than it is today? The majority of people that hold it are long-term investors.”
