They are two different things. I give you definitions below and think in your case you need to use cryptoeconomy

"...The crypoteconomy refers to a growing array of emerging technologies, rooted in public-key cryptography, that enable individuals to engage in a huge range of economic activities that were previously possible only through financial intermediaries.
In building this suite of technologies, the market is behaving with astonishing intelligence, turning out innovations every day that would have been inconceivable a decade ago. Whole worlds of code are being woven by a decentralized network, seeking to solve universal human problems concerning finance, monetary economics, contracts, insurance, property titles, and every other form of human engagement.
The pace of development is red hot. Every innovation is being tested against user experience and investor enthusiasm. You can follow the market in real time, with digital currencies and other forms of digital assets soaring to new heights and making millionaires by the day. It’s no longer just about Bitcoin. It’s about thousands of new services being built on top of distributed platforms such as Ethereum, a code environment that does for crypto what iOS first did for the app economy...."

"Cryptoeconomics is a concept as well as a new term and, hence, has no official definition yet.
...cryptoeconomics is “a formal discipline that studies protocols that govern the production, distribution and consumption of goods and services in a decentralized digital economy. Cryptoeconomics is a practical science that focuses on the design and characterization of these protocols.”
The Ethereum Wiki defines cryptoeconomics as “the combinations of cryptography, computer networks and game theory which provide secure systems exhibiting some set of economic dis/incentives.”
While the founder of TheControl, Nick Tomaino, explains cryptoeconomics as “the study of economic interaction in adversarial environments. In decentralized P2P systems that do not give control to any third party, one must assume that there will be bad actors looking to disrupt the system. Cryptoeconomic approaches combine cryptography and economics to create robust decentralized P2P networks that thrive over time despite adversaries attempting to disrupt the network.”

In simple terms, cryptoeconomics is a new field of study that analyses economic interactions in the decentralized digital economy that was pioneered by bitcoin. It is the foundation on which cryptocurrencies and digital assets are built on..."
