想了解区块链，你先要知道这些

最近越来越多的人在聊基于区块链的比特币，以太币、瑞波币、EOS……上千种基于区块链挂的虚拟币已经在我们身边经常听到了。风险极大的虚拟货币的涨跌在一天之内能到50%，依然按耐不住童鞋们的骚动的心情，就好比当年互联网刚发明的时候面临的财富重新分配，区块链比人工智能率先进入应用场景，拥有无限的未来想象空间。随之而来的炒币也像一场巨大的赌局已开盘，你当然不想错过这个财富重新分配的机会，但是风险又很高，你既可以小赌怡情，你也可以放手一搏，承担后果。

但是我今天主要聊的倒不是炒币或者区块链本身，而是方法论：如何快速的突破重围高效率的学习这些新玩意儿。我今天想让大家如何在2018年科学的进行互联网冲浪，让你通过全球顶级的内容服务商，更好的去了解发生在我们身边的一些事情。我希望我的努力能够让周围的朋友们与硅谷与下一代的科技靠的更近。只需要10分钟，你就可以毫无阻碍的去了解和学习发生在最前端的科技。如果你不喜欢看枯燥的文字，差劲的翻译，填鸭式的教育视频，那去油管搜索那些浅显易懂的视频会让你知道原来学习方式也是有各种途径。

It’s pretty good to use Project Fi sim card if you love to track your outdoor events.

Now I am in Shanghai and I also bring back the Project Fi sim card. Recently Google announced that international travelers with Project Fi can access to High Speed internet in over 135 countries, while China is one of them. I am so excited that when I using T-mobile in China, the speed is limited to 2G/Edge that makes the service almost unavailable. So this time I am so excited to see how Project Fi works in China. After a few weeks, I did some tests and here are my experience.
