Cronos vs OKB
Cronos (CRO) and OKB (OKB) both sit in the exchanges category, so they compete for the same slot in a portfolio. Cronos launched in 2018, 1 year before OKB. Cronos uses Proof of Authority (Cronos) and OKB uses — (token de exchange). 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 Cronos and OKB?+
Cronos (CRO) launched in 2018, uses Proof of Authority (Cronos) and has a maximum supply of 100.000M. OKB (OKB) launched in 2019, uses — (token de exchange) and has a maximum supply of 21M. 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?+
Both have a hard cap: 100.000M for Cronos and 21M for OKB. A cap limits future issuance, but it says nothing about demand — and demand is what sets the price.
Do they use the same technology?+
No: Cronos uses Proof of Authority (Cronos) and OKB uses — (token de exchange). 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.
