1. Only invest money you don't need for life. Virtual coins could be stolen from trading plattforms and it is highly risky.
2. Don't invest money from your family & friends.
3. Most of the trading strategies for the traditional stocks are valid.
4. Read for e.g. http://www.libra.tech/blog/the-beginners-guide-to-bitcoin-trading/
5. Be always carefully with your investments. Start small and may be with virtual trading accounts where you can train.

Be aware: This no recommendation for winning money, trading is always highly risky and you need good nerves.
