闲聊几句比特币和区块链

比特币最初是由一个日本人构建出来的，初衷是为了实现去中心化。我炒过一段时间虚拟货币，挺刺激的。我们都知道比特币受到墙街大佬的关注，一度把期货价格炒到五万刀。太火的时候，国家出面打压或者禁止交易，价格波动比迪斯尼的过山车都凶猛。也有人在最火的时候，把房产抵押出去的。这绝对是玩大了。

曾经有朋友问我，是不是应该炒比特币。我告诉他，如果你有很多钱，可以拿一些丢了都不会有感觉的量出来，炒一下，感觉一下究竟是怎么个玩法，权当长长见识，否则没有必要玩这个。

还有一个朋友问我，国内好友拜托她在美国帮忙炒比特币，是不是应该帮这个忙。我告诉她，情愿借给他钞票，都不能帮这个忙。除非你想几辈子断交。因为虚拟货币交易是24小时不间断运营的，价格波动很大，庄家会套现，你怎么保证他赚钱？别说他不在乎赔本，进了赌局的人，都想赢。

虚拟货币在疫情期间又火爆过一次。区块链技术，我没研究过。这个技术看起来大有发展前途。现在抄一段英文：

Much of the initial private blockchain-based development is taking place in the financial services sector, often within small networks of firms, so the coordination requirements are relatively modest. Nasdaq is working with Chain.com, one of many blockchain infrastructure providers, to offer technology for processing and validating financial transactions. Bank of America, JPMorgan, the New York Stock Exchange, Fidelity Investments, and Standard Chartered are testing blockchain technology as a replacement for paper-based and manual transaction processing in such areas as trade finance, foreign exchange, cross-border settlement, and securities settlement. The Bank of Canada is testing a digital currency called CAD-coin for interbank transfer. We anticipate a proliferation of private blockchain that serve specific purposes for various industries.

时代真的不同了。提到高科技，人们会想到硅谷。个人感觉，金融机构，科技也不弱。
