Bitcoin (BTC) is a digital currency, invented by "Satoshi Nakamoto" in 2009, that is limited to just 21,000,000 units. As the price of bitcoin has risen, transaction fees have become much more expensive, making it impractical to use bitcoin for smaller, every day purchases. Bitcoin’s use case has evolved over time from a peer-to-peer currency into a store of value (“digital gold”)..​​​​​​

Ethereum (ETH) is not a currency, it’s a decentralized, blockchain based computing platform that facilitates smart contracts. The supply of Ether is UNLIMITED. More than 90,000,000 Ether are currently in circulation, which is six times more than the current circulating supply of bitcoin. Because many ICOs trade ETH for their tokens, when they later sell Ether to raise funds for their businesses, the price of ETH can swing wildly.
