Today, Bitcoin mining consumes more electricity than some countries. For example, in 2018, about 70 terawatt-hours of electricity were spent on mining, which exceeds the energy consumption of countries such as Argentina or the Netherlands.
In 2017, Bitcoin reached its all-time high, exceeding $19,000 per unit. However, a year later its cost dropped to $3,000.
In 2013, the first case of major fraud using Bitcoin was recorded. Hackers hacked the Mt. Gox and stole more than 850,000 bitcoins, which at that time amounted to about $480 million.
Bitcoin was the first cryptocurrency, but today there are more than 2,000 different types of cryptocurrencies. Some of them, such as Ethereum or Litecoin, also have great popularity and value.
