The 2017-2018 Bitcoin boom and bust

2017 was a year of many new records for the BTC/USD exchange rate, as the price of bitcoin soared to then-unpresidented levels. It climed to 2,000 USD in May, reached 4,000 USD in August, 5,000 USD in September, and peaked at a whopping 19,783.21 USD on December 17. On December 22, it had fallen to below 14,000 USD.

The 2018 Bitcoin crash occured soon after the end of 2017. Between January 6 and February 6, the bitcoin price fell by roughly 65%.

The 2018 Bitcoin crash was a part of the 2018 Great Crypto Crash, as several other cryptocurrencies followed the trajectory of bitcoin (albeit at lower levels), seeing record-breaking growth in late 2017 and then falling dramatically in early 2018. In the first quarter of 2018, the cryptocurrencies’s market capitalization lost over 340 billion USD, which is the largest loss in cryptocurrencies to date.

How new bitcoins are created

New bitcoins are created through a process known as bitcoin mining.

The Bitcoin network needs computer power to work, and it rewards the donors of computer power with newly created bitcoins. Because of this, new bitcoins are constantly being created. So far, this hasn’t caused any inflation, because the interest in aqauiring bitcoins have rose faster than the creation of new bitcoins.

To put it simple: A bitcoin miner donates computer resources to the Bitcoin network by letting the network use their computer to verify and log bitcoin transactions. In exchange, the bitcoin miner gets newly created bitcoins.

What’s a Bitcoin wallet?

In order to prove that you are the owner of a certain bitcoin, you need to provide the Bitcoin network with certain data. This data can be stored digitally or physically. The storage medium is commonly referred to as a Bitcoin wallet.

The most well-known form of Bitcoin wallet is the electronical one, where you store the information in digital form on your own computer harddrive. A downside with this is that you risk losing the information in case of computer trouble.

Another option is to store the information physically, e.g. in the form of print outs on paper. Of course, that option comes with downsides too.

If you don’t want to store information in your own computer nor physically, there are providers available online that will let your keep your Bitcoin wallet on their server.

Bitcoins are transferred through the Bitcoin network, without using any banks.

  3. María orders her wallet to transfer 2 bitcoins to Erik’s Bitcoin address. A private key stored on Marias computer is used to generate a digital signature.
  4. The digital signature is confirmed by the Bitcoin network, using the public key.
