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
Your advice is also good, but we should not scare the newbies too much about trading, if one learns and understands trading, it is not that difficult. All they need is knowledge and for that, they need dedication and focus, and they can eventually become good traders. I think newbies should do spot trading because the risk of losses in futures trading is high, and the chances of profit in futures trading are very low for unlearned and less knowledgeable traders.
We need to tell newbies that trading requires patience and thoughtful decision-making. People who are quick to get hyper and lose heart often face failure in the field of trading. That's why, it is important for a trader to have a lot of patience and control over their emotions when entering the cryptocurrency market.
