1. If you don't have enough money to invest in the secondary market, you can participate in on-chain testnet interactions, galaxy missions, and airdrops with minimal costs to earn your first pot of gold.

2. The effect of getting rich quickly with low-quality coins is also very strong; if you catch a coin and buy it at the front row, you won't need to work hard for the rest of your life.

3. NFT whitelist; there are many NFT projects on Twitter that offer free minting on the whitelist with almost no cost (there are many ways to obtain whitelists, most of which have no cost, such as surprise lotteries, DC group levels, bringing people to DC groups, AI drawing, etc.). The price of a blue-chip whitelist on the secondary market varies from 50-500 USD; the whitelist price depends on the secondary market conditions.

4. This is the method I least recommend, contracts; most inexperienced people will likely face liquidation, and there are many cases of getting rich quickly.

5. GPU mining requires certain computer skills; participate in the early mining activities of new projects on Twitter, where you only need to cover electricity costs.

Once you have money, you can consider the secondary market.

- Research and education: Deeply learn about the cryptocurrency market, blockchain technology, and market trends to avoid blind investments.

- Diversified investment: Do not put all your funds into one project or coin to reduce risk.

- Arbitrage opportunities: Utilize price differences between different trading platforms for arbitrage, but be mindful of transaction costs and risks.

- Stablecoin strategy: Use stablecoins to avoid market volatility while looking for low-risk investment opportunities.

- Mining or staking: If conditions allow, participate in mining or staking for additional income, but consider electricity costs and equipment investment.

- Trading strategy: Learn technical analysis and fundamental analysis, and develop short-term or long-term trading strategies. Be careful not to overtrade (overtrading may lead to more losses).

- Utilize DeFi: Earn interest or participate in liquidity mining through decentralized financial platforms, but understand the risks of smart contracts.

- Risk management: Strictly set stop-loss points, control investment ratios, and avoid losing everything due to one or two failures.

- Community participation: Join active crypto communities to get the latest information and potential investment opportunities.
