I've been having some conversations lately comparing Bitcoin (BTC) to Ethereum (ETH). Here is my take (TLDRs at the bottom of each section):
Key differences: 1. Monetary Policy, 2. Smart contracts, 3. Proof of Work vs Proof of Stake, 4. Scaling
Monetary Policy:
Bitcoin has a capped supply at 21 million bitcoins. Solid monetary policy for what BTC is seeking to be - an inflation resistant store of value comparable to gold.
Ethereum (starting in July) has a supply that is stable or declining relative to how much activity is happening on ETH. High level, transaction fees on ETH are currently paid to miners, but as of July a portion of transaction fees will go to miners but much of it will be "burned".
This meets the same store of value need that BTC does, only better in my opinion.
TLDR; BTC is a good inflation resistant store of value. ETH is a better inflation resistant store of value.
Smart contracts:
BTC doesn't have them, ETH does. Support of smart contracts means that Ethereum is a platform for entire industries to be built on top of it. Decentralized finance (DeFi) is the biggest so far. There are ~$70B locked up in DeFi protocols right now, and increasing ~40% per month. This is solving real world needs and will be an incredible force for good (especially bringing banking/financial services to the poorest people in the world, but also bringing better banking to all of us).
More industries will be built on ETH; The NFT revolution is another emerging industry in the early stages. There will be more. Both DeFi and NFTs are serving real human needs in a really powerful way.
So BTC is an inflation resistant asset. ETH is an inflation resistant asset + platform. And the two synergize. The more ETH is used as a platform, the more value accrues to the asset.
TLDR; ETH is a platform for additional applications. BTC isn't.
Proof of Work vs Proof of Stake:
Currently both use proof of work. ETH will finish their switch to proof of stake Q4 2021 or Q1 2022. Proof of stake is more secure (though proof of work is very very secure too), and requires 99.89% less electricity, less use of computing hardware, and improves the functionality of the blockchain in several other ways.
TLDR; BTC is secure. ETH is more secure and more resource efficient.
Scaling:
BTC is intentionally not scalable. They seek to remain simple, secure and unchanged at the cost of scalability. ETH is in the process of scaling in two key ways: Rollups and Sharding. Rollups come this year, sharding over the next 2-3. Between the two, ETH will be able 10,000x - 100,000x more scalable than BTC. This scaling will further empower the applications built on top of ETH to provide high quality services at very low cost to people across the world.
TLDR; BTC is not scalable and seeks to remain so, ETH is more scalable and will soon become much much more scalable.
Conclusion:
Both BTC and ETH are good and both are improving the world. But I think ETH is an order of magnitude more important and transformative than BTC.
What about Doge? I think it's a bet on social media and the populist movement. But it doesn't really have anything to do with crypto. I think Doge has more to do with GME than it does to BTC and ETH.
