It is impossible to keep Bitcoin and Ethereum out of the conversation whenever we talk about cryptocurrency. Bitcoin is the first cryptocurrency that came into existence in the year 2009. All other cryptocurrencies are referred to as Altcoins (alternative to Bitcoin). But over time, Ethereum has established a name for itself. 

1. Type of blockchain technology

There are three types of blockchains -

• only currency
• currency + business logic
• only business logic

While Bitcoin is just a currency, Ethereum is a currency as well as ledger technology used by businesses to create new programs. 

2. Speed of transaction

Ethereum was created in 2013, focusing on the limitations of Bitcoin. Ethereum transactions are undoubtedly faster than Bitcoin transactions. It takes 10 minutes to process a block of Bitcoin transactions. On the other hand, it takes 10-20 seconds to process a block of Ethereum transactions.

3. Utility

Bitcoin was created as an alternative to fiat currencies and has emerged as a medium of exchange. Bitcoin has emerged as a gold standard and has attracted investments from institutions. Ethereum on the other hand is intended to facilitate immutable contracts. Ethereum facilitates the development of distributed applications and smart contracts. The Ethereum network can be used to create new cryptocurrencies or tokens, which can be distributed on different blockchains.

4. Supply

There can only be 21 million Bitcoins that can be mined. And no more Bitcoins can be mined after that. This makes Bitcoin an exclusive cryptocurrency. FOMO is an important factor in the popularity of Bitcoin. On the other hand, there is no cap as to how many Ethereum can be mined.
