A good tip for beginners in cryptocurrency trading is:

1. Start researching and learning: Before you invest any amount, learn the basics. Learn how cryptocurrencies work, what blockchain technology is, and how wallets and platforms work.

2. Invest as much as you can afford to lose: The cryptocurrency market is highly volatile, so invest an amount that you are prepared to lose.

3. Don't put all your money in one asset: Try to diversify your investments across several currencies to reduce risk.

4. Keep your wallet safe: Make sure to use secure wallets and enable two-factor authentication. Cold storage may be a better option for some long-term investments.

5. Be patient and avoid panic decisions: Price volatility may prompt some to sell quickly, but keeping your cool and making informed decisions will reduce the risks.
