The biggest money making slot in crypto space is to be
1. a developer
2. build crypto wallets for new projects
3. find bugs in the system of many new projects
yes some paid for security breaching and all that stuff, rendering professional services is the best way to make money in crypto space now
Till today I can't build wallet or any software myself, I don't even know where to start, finding bugs in projects system is even another level of expertise, all these aren't for people like me so we prefer promoting new projects instead
