Bitcoin vs. Ethereum

Bitcoin is a “cryptocurrency.” Bitcoin and other cryptocurrencies are competing against existing money (and gold) to replace them with a truly global currency.

The promise of Bitcoin is that it is:

  • A global currency which allows individuals to own their own money (without having to rely on national banks).
  • Lower fees for transferring money across geographic borders.
  • Financial stability for people who live in countries with unstable currencies. (e.g. In 2016, the Venezuela’s currency hit an inflation rate of 800%). In addition, two-thirds of the current global population has no access to banking, or limited access — Bitcoin is changing that.

Ethereum is a “token.” What Bitcoin does for money, Ethereum does for contracts. Ethereum’s innovation is that is allows you to write Smart Contracts: basically any digital agreement where you can say “if this” happens, “then something else happens.” For example:

  • If I vote for the President, then my vote is official and no one else can vote as me.
  • If I sign my name on this document, then I own the car, and you no longer own the car.
  • Up until now we’ve carried out these agreements with a signature at the bottom of a paper document. Ethereum dramatically improves this model because it is digital, and proof of the transaction can never be deleted.

Comparison chart: Bitcoin vs. Ether

Bitcoin (BTC) Ether (ETH)
What is it? A currency A token
Inventor Satoshi Nakamoto Vitalik Buterin; Other co-founders include Gavin Wood and Joseph Lubin
Went alive January 2009 July 2015
Supply Style Deflationary (a finite # of bitcoin will be made) Inflationary (much like fiat currency, where more tokens can be made over time)
Supply Cap 21 million in total 18 million every year
Smallest Unit 1 Satoshi = 0.00000001 BTC 1 Wei = 0.000000000000000001 ETH
New token issuance time Every 10 minutes approximately Every 10 to 20 seconds
Amount of new token at issuance 12.5 at the moment. Half at every 210,000 blocks 5 per every new block
Utility Used for purchasing goods and services, as well as storing value (much like how we currently use gold). Used for making dApps (decentralized apps) on the Ethereum blockchain.
Price Around $17,500 at the moment Around $800 at the moment
Purpose A new currency created to compete against the gold standard and fiat currencies A token capable of facilitating Smart Contracts (For example: a lawyer’s contract, an  exchange of ownership of property, and voting)

Ethereum vs. ether

Let’s go a step further:

Bitcoin itself is two things: (1) it’s a digital currency known bitcoin (lowercase, also referred to as BTC) and Bitcoin is a technology (also known more generally as  blockchain). Both are called the same thing which admittedly can be confusing for newbies.

  • Bitcoin = The name of the Bitcoin network
  • bitcoin = The currency (or BTC)

With Ethereum it’s similar, but slightly different: the token is called ether (or ETH) and the network is Ethereum.

  • Ethereum = The Ethereum network
  • ether = The token (of ETH)
