Tbf, you can buy and hold and not give a crap about a 5-7% decrease this week.
If you know you will potentially be able to 5-8-10x your money in the future (look at the big picture, zoom out lmao).
But yeah, just pay attention to the levels and cut losses as soon as possible.
You can wait till it becomes clear and looks ' obvious ' to buy and then the market won't carry you away, like Its doing to me atm.
