China bans crypto events in Beijing

Last week the government of China banned crypto events in Beijing, over the counter (OTC) trading through Alipay and crypto related WeChat accounts. WeChat, the social media platform has over 1 billion users. The majority of the crypto related accounts on WeChat endorsed scam coins and created crypto trading “hype” according to officials. In September, 2017 China banned fiat to crypto trading exchanges along with Initial Coin Offerings (ICOs). These bans will slow down the cryptocurrency and blockchain adoption in China which is ironic because China has already spent more than $3 billion in funding blockchain projects this year.

These funds will hold massive amount of Bitcoin which will cause price manipulation and huge influence on the crypto market.


Bitcoin's Growing Energy Consumption

The process of mining Bitcoin is becoming more energy intensive. The amount of electricity Bitcoin mining uses is 1% of the world’s energy production. Anything that consumes 1% of our world’s energy must be very important part of the global economy. Concerns around Bitcoin’s energy consumption is not only environmental, but also economic too. Saving energy means saving costs. Bitcoin mining is growing in areas where there is cheap renewable energy. This will incentivize firms to develop renewable energy sources that will allow  increased power consumption without having any negative impact on environment.

Crypto word of the week

Bitcoin ETF stands for Bitcoin Exchange Traded Funds. A Bitcoin ETF is a fund that holds Bitcoin and creates shares that represent the value of Bitcoin the fund is holding. A fund manager holds Bitcoins and investors get a share in the fund. ETFs are traded like a stock during the day when stock exchanges are open. It allows traditional investors to speculate on Bitcoin without actually owning a Bitcoin. This way Bitcoin will become more available to a lot more investors. You don’t have to deal with complex things like holding your private keys as your fund manager holds Bitcoin on behalf of you. This also means investors will lose the rights and responsibilities that a Bitcoin key holder has. For example if there is a chain split you won’t be able to have the newly created coins on the forked chain.

Quiz answer

What is Proof of Work?

The correct answer is : “B”

Proof of Work (PoW) is a piece of data that requires enormous amount of computation to be produced. It proves that enough energy is spent to validate a new block and no one spent the same coin twice. Once the PoW is produced others can easily verify if it has correctly validated all the transactions. Proof of Work is like a solution of a giant sudoku. Everytime the sudoku is solved, it resets itself automatically. A completed sudoku puzzle can be quickly verified. In Bitcoin’s case the giant sudoku resets itself every 10 minutes. Proof of Work is a unique data that cryptographically links the new block to the previous one.
