This is why it's very important we have very safe, very decentralized and easy to use crypto. You could build the right ecosystems and get people earn, reward and trade with each other with moderately deflationary cryptocurrencies/tokens.
It's also risky (in my opinion) to rely too much on centralized usage of cryptocurrency. So you have to worry about that also.
I would invest long-term in a well decentralized crypto driven by right principles, rules and consensus
