You could use proper programs that can notify you if something big happens on the market.
Or just deploy some safety nets for when you are not in front of the computer (with the obvious risk of false changes in trend and the risk of having too much money on online services).

But don't worry. Sooner or later Bitcoin will recover and even get higher.

The market is for the ones very agile and that know the game very well. You don't seem to fall into that category so you better stop trading and better play the waiting/hodling game.
