1. Knowledge first
Yes, that's right, knowledge is crucial. Not only knowledge about crypto specifically, but also knowledge about financial management, emotional and personal control, and risks management that must be possessed to minimize existing risks.
2. Spot trading.
Actually, trading also has a big risk, but at least, Spot trading is much lower risk than using leverage or Future trading. And, trading is also risky, so we must have adequate knowledge about the analysis of various coins that we will trade, and understand when to buy and sell them, and understand the strategy well and wisely.
3. Airdrop Farming
Maybe this includes several other free programs such as bounties, signature campaigns paid BTC, Top altcoins, or Stable coins. However, we really have to be smart in choosing which programs are worth doing.
4. Investing.
Maybe there are many coins that are worth investing in. but for beginners, I can only dare to suggest Bitcoin as the main investment, followed by ETH, BNB, and maybe top coins, but all of this still has risks.
