Bitcoin is a Stable Investment when Markets are Unstable

The looming clouds of uncertainty are hanging over the markets, as the saga of events leading to 2016 presidential elections is still unfolding. The markets showed a 2% surge on November 7, after FBI once again cleared Hillary Clinton regarding her private servers’ emails. Nevertheless, market analysts argue that the shock from a plausible Trump’s victory will likely hit the markets even harder than the Brexit (which cost investors about 2$ trillion in one day).

In this volatile environment, investors are looking for safer investments and some of them are opting for the virtual currencies such as bitcoin. Bitcoin is the most popular virtual currency in the market with more than 100,000 transactions per month. Bitcoin does not have a physical existence and is not controlled by a central authority the way Canadian dollar is controlled by Bank of Canada. Its backbone is essentially computer code, distributed among a wide network of servers called ‘nodes’. Transactions made by bitcoins are anonymous and a record of all the transactions to date is called a ‘blockchain’. Blockchains can be best understood as ledger account, which is openly available online. Creation of bitcoin takes place when a node performs a large amount of calculations to add a block to the blockchain; this process is commonly referred to as ‘mining’.

Virtual Currencies such as bitcoin, always had their place in the tech community, but what makes bitcoin attractive to financial industry? For the majority of its lifetime, bitcoin has been on the shadier side of the economy; the tax authorities and the law enforcement did not exactly know how to treat it under the law and remained suspicious of its potential for illegal transactions. But in recent years, many have caught up including Canadians, who passed their first law in June 2014 for regulating the use of bitcoins.

 

Bitcoin is Fair, Stable, Safe, and Secure *

In contrast to paper currency, bitcoin transactions are always recorded, making it easy to keep track of the currency on the market. Also distribution of blockchains among nodes globally, makes the transactions’ records secure and almost impossible to alter. These two qualities convinced the Swedish National Land Survey to consider bitcoins as a tool for transaction and record keeping, as it is many times faster than the current manual methods requiring lots of paper work. Convenience afforded by the bitcoin is an important factor in attracting people; there are currently more than 100,000 merchants that accept bitcoins with hundreds of ATM machines around the world. Bitcoins cut the middleman in the transaction, meaning that buyer and seller interact directly instead of through credit card companies and this eliminates the transaction fee. Like non-virtual currencies, bitcoin’s value fluctuates over time. However, as the political volatility increases, bitcoin locks steps with gold, making it an attractive investment hedge in the times of uncertainty. For all of these reasons, investors are considering bitcoin as a viable investment option; putting its star on a rising path.

Robots build after cockroaches will save lives

Robots build after cockroaches will save lives

Cockroaches. They are not nice or fluffy and spotting them indoors means trouble. In our minds, cockroaches are associated with mold, dirt, and cavity and they are in fact suitable carriers for diseases such as E-coli and salmonella. However, behind its repugnant appearance there is one of the most fascinating creatures living in our environment.

They are thought to be the world oldest pests and legend has it that they will survive the nuclear apocalypse. During their long evolutionary history, cockroaches have developed high degrees of resistance to environmental risks. Their population experiences a rise in the hot seasons and despite the efforts of pest control companies, cockroaches often become gradually resilient to pesticides.

cockroaches can stand pressure up to 900 times their weight

The extraordinary physique of the cockroaches have inspired scientist in developing robots that can potentially save many lives. The flexible nature of cockroaches’ bodies enables them to swiftly squish throw crevices of only two pennies (one tenth of an inch) wide. Researchers at the University of California, Berkeley have produced a prototype robot modelled after cockroaches’ physique that can be released into the cracks and vents of rubbles after an earthquake to quickly locate survivors.

Cockroaches’ locomotive abilities let them move as fast as five feet per second, allowing them to squish through gaps and cracks by reorienting their legs to one side. Moreover, cockroaches are highly resilient against extreme pressure and they can stand up to 900 times of their body weight. This enables cockroaches to survive crashes under the rubble, making them strong and yet agile. Robots designed by researchers at UC Berkeley, which were modeled after cockroaches, were named CRAM for compressible robot with articulated mechanisms. The shell of the robot can be compressed by up to 20 lb and its unhinged legs allow it to move under compression.

 

So cockroaches amazing capabilities are not only inspiration for urban myths, they inspire scientists, too.
