According to ChainCatcher, Vitalik Buterin responded to netizens on the social platform and said: “The type of applications I want to see are those that work in a sustainable way; applications that do not sacrifice principles (no permission, decentralization, etc.).
I think DEXs are awesome, I use them every week. I think decentralized stablecoins like RAI are awesome. I also think Polymarket is awesome.
I think USDC is not as good as RAI, but as a practical matter, we have to respect that it is very convenient and a lot of people are using it. It is very useful for me personally when making international donations, which is much more convenient than banks. We are trying to make the global economy and society more open and free, and people in emerging markets using stablecoins to trade freely is a real life use case that is happening everywhere.
USDC on Ethereum is also much better than account-to-account transfers within centralized exchanges, which also happens frequently. If we get a lot of people using USDC, that creates a situation where it's easier for people to switch to other more decentralized stablecoins.
The things I don't respect are basically things where the traction comes from some temporary source and has no sustainability. I'm not excited about the 2021 liquidity mining craze because it's clear that it comes from token issuance that is fundamentally temporary.
If someone tells me, ‘Here’s where I can get a nice return on my money,’ my question is always, ‘Where is the return coming from?’ Who’s on the other side of the transaction, who’s paying the return? If there’s a concrete answer to that question, and there’s good reason to believe that the answer will still be true in five years, then I’m going to be very excited about it.”
