Here is my suggestions if you want to make money from crypto;
1. Knowledge first
2. Spot trading.
3. Airdrop Farming
4. Investing.
1. Knowledge First:
This is foundational. If you don't have this you are liable to fall to scam. You need to learn about wallet, exchanges, dexes, and conviction and patience.
2. Spot Trading :
This is a tangible skill that differentiate you from another person. With this you know how to make money trading. But ensure you stay away from futures trading. Use spot trading to start.
3. Airdrop Farming:
This is a low risk way to make money in crypto. Learn the popular airdrop in crypto space. Currently Telegram mini app farming is what is reigning.
4. Investing:
What will help you here is physiological skills like emotion management and patience. You will also need to learn when to invest and when to take profit.
To conclude this, you can learn this from credible YouTube channels and Coinmarketcap/Coingecko education channels.
All that you pointed out is very much valid no doubt, but I just feel like adding more to it, because you mostly talked on how to make money and you didn't talk on measures that should be taken not to fall prey in your investment and not to lose money.
And one of them to me is greed, greed in crypto can be very destructive to an investor because you already knows that aside Bitcoin, it's very dangerous to invest in any other alt coin or shit coin there about, but due to greedy, you will still go ahead to invest in shit coin because of 50x or 100x, which in most cases, it's more likely to end in losses, and it's because of greed you will even get to that space in the first place.
Another thing is lack of knowledge on how scammers operate, as a newbie, if you don't know how scammers operate and how to counter them, you are very much bound to lose money at some point in your investment journey.
