For those who are just starting out, take note of my suggestion:
1. Research the currency before investing and draw your own conclusions.
2. Avoid following anyone's advice. Always do what you are sure is right.
3. Start small and "poke around" with the app as much as possible.
4. Be patient, remember that it is an investment. And investments sometimes take time to show returns.
5. Pay attention to the app's fees.
6. Avoid selling when prices are low.
7. Never buy when prices are high.
