Dai vs USD Coin

Dai (DAI) and USD Coin (USDC) both sit in the stablecoins category, so they compete for the same slot in a portfolio. Dai launched in 2017, 1 year before USD Coin. Dai uses — (token sobre Ethereum) and USD Coin uses —. This page compares what can actually be verified about each protocol — nobody can tell you which will be worth more, and this page does not try to.

Cryptocurrencies are a highly volatile asset class without the protections of regulated funds: you can lose your entire investment. This comparison is educational content about the technical characteristics of two protocols, not a buy recommendation or a price forecast.

Frequently asked questions

What is the difference between Dai and USD Coin?+

Dai (DAI) launched in 2017, uses — (token sobre Ethereum) and has a maximum supply of ∞. USD Coin (USDC) launched in 2018, uses — and has a maximum supply of ∞. Beyond the numbers, they were built for different purposes — see the description of each below.

Which one will be worth more?+

Nobody knows, and anyone telling you otherwise is guessing. Crypto prices depend on adoption, regulation, liquidity and sentiment, none of which can be forecast from a protocol's specs. This page deliberately compares only what is verifiable today.

Which has the scarcer supply?+

Neither has a hard cap on issuance (∞ and ∞). That is not automatically bad: many protocols use ongoing issuance to pay for network security, but it does mean supply is not fixed.

Do they use the same technology?+

No: Dai uses — (token sobre Ethereum) and USD Coin uses —. The consensus mechanism affects energy use, how the network is secured and how new coins enter circulation.

Should I hold both?+

That is a question about your risk tolerance, not about these two protocols. Crypto is a volatile asset class where you can lose your entire investment, and holding two coins in the same category adds far less diversification than it looks — they tend to move together.
