Welcome to the forum. Depends what country you're in, but:
1. Do not store your bitcoin on exchanges or webwallets.
2. Do not daytrade.
3. Do not invest in cloudmining (Most are ponzis, fractionally reserve mine, or charge too high fees = you will never ROI).
4. Do not mine until you have done at least 100 hours of research.
5. Do not invest your bitcoins in any investment schemes.
