The thing that I often ask startups on top of Ethereum is, 'Can you please tell me why using the Ethereum blockchain is better than using Excel?' And if they can come up with a good answer, that's when you know you've got something really interesting.

I love this stuff - bitcoin, ethereum, blockchain technology - and what the future holds.

Abigail Johnson

We set up a small bitcoin and ethereum mining operation... that miraculously now is actually making a lot of money.

Tokenization applies to scarce assets. Today, the most appropriate thing to tokenize is something that's purely digital. Bitcoin and ethereum are the canonical.

Balaji Srinivasan

In 2017, people have realized there isn't going to be one crypto to rule them all. You're seeing vertical solutions where XRP is focused on payment problems, Ethereum is focused on smart contracts, and increasingly, bitcoin is a store of value. Those aren't competitive. In fact, I want bitcoin and Ethereum to be successful.

Brad Garlinghouse

Ether is the token of the Ethereum network, which is focused on disrupting contract law.

Working on a token is similar to working on a startup: higher risk and lower initial impact but higher upside potential. How core protocol work is best funded beyond the initial Ethereum Foundation endowment is an open question, but likely further out.

Fred Ehrsam

Working on Ethereum could be similar to working at a Google: lower risk with broad impact right away. Working on a token is similar to working on a startup: higher risk and lower initial impact but higher upside potential.

Fred Ehrsam

There is nothing that Bitcoin can do which Ethereum can't. While Ethereum is less battle-tested, it is moving faster, has better leadership, and has more developer mindshare.

Fred Ehrsam

Ethereum may make monetary policy decisions like, 'Let's do 1% inflation to support the ongoing development of the Ethereum protocol.' A token built on Ethereum might want to do the same.

Fred Ehrsam

Make no mistake - Ethereum would never have existed without Bitcoin as a forerunner. That said, I think Ethereum is ahead of Bitcoin in many ways and represents the bleeding edge of digital currency.

Fred Ehrsam

Ethereum has taken what was a four-function calculator of a programming language in Bitcoin and turned it into a full-fledged computer.

Fred Ehrsam

Sales conducted on-chain through smart contracts couldn't really be done before Ethereum, which is why they are a newer concept. I think this style will become the most common over time.

Fred Ehrsam

Ethereum will be a first-class citizen on Coinbase.

Fred Ehrsam

When you drill down, blockchains are really a shared version of reality everyone agrees on. So whether it's a fully immersive VR experience, augmented reality, or even Bitcoin or Ethereum in the physical world as a shared ledger for our 'real world,' we'll increasingly trust blockchains as our basis for reality.

Fred Ehrsam

Ethereum is enabling a new form of financing in ICOs that is like a massive gravitational pull - dragging every entrepreneur with a sense for opportunity into its blackhole-level gravity.

Gil Penchina

It's clear to me now that Ethereum is the new currency of the Internet. It's way ahead of where Paypal was in its day, and it's much more exciting to its customers than Paypal ever was.

Gil Penchina

Can we all please - I don't want anybody buying cryptocurrencies, okay? Stop it. Enough already. Or buy Bitcoin, don't buy Ethereum.

Jensen Huang

Ethereum exists because it enables developers to write smart contracts better than Bitcoin in the near-term. Zcash will exist because it will attempt to do privacy better than Bitcoin in the near-term, and the token gives you access to the anonymity protocol.

Nick Tomaino

Polychain is investing in blockchain assets. We do not invest in private companies or hold shares in private companies. We invest purely in tokens or digital assets, and those include assets that people are familiar with, like bitcoin and ethereum, as well as very early-stage projects.

Olaf Carlson-Wee

Application-specific tokens, or app-tokens, are built on top of existing general-purpose blockchains like Bitcoin and Ethereum. For the first time, open-source project creators can directly monetize their open-source network.
