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 PayPal USD?+
Dai (DAI) launched in 2017, uses — (token on Ethereum) and has a maximum supply of ∞. PayPal USD (PYUSD) launched in 2023, uses — (token on Ethereum and Solana) 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 on Ethereum) and PayPal USD uses — (token on Ethereum and Solana). 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.
