That's quite tough, and I think you need time management.
But always remember that your job is your priority, and as a teacher, your primary focus should be on your job and your students.  Your teaching duties and obligations must be fulfilled before dedicating time to Bitcoin trading.  Set clear boundaries to avoid any conflicts of interest or distractions during your work hours.

If you really want to trade it might you may consider using automated trading tools or setting up specific alerts to help manage your Bitcoin trades more efficiently.  These tools can monitor the market for you and execute trades based on predefined parameters, reducing the time and effort required on your part.  But remember these tools are just a tool to make you more profit, they work on behalf of you so it depends on your decision how the trading bot will work.

Well, good luck.
