There are many ways but as you are newbie, you have many restriction. Like you shouldn't jump Crypto trading, that would be loss project for you. Rather bounty and airdrop could be good opportunity for you. You just need to invest your time and need to gain knowledge about Crypto field so that you can have ability to analysis project and thus you can find good project to go with. Rather you can be web developer or designer, it have good value and income in crypto
I would suggest the realistic way which is just go and get a job somewhere that pays decent, with no skill then obviously it's going to be hard labour job but few months of salary is good enough to start investing in Bitcoin. Trading is recommended if the taxation is favorable or else just keep on investing in Bitcoin with the money that he makes in other jobs.
