So you are basically saying that investors buy low and sell high.
It's the only rule that truly applies to investments.
You can avoid looking at the price, simply by finding an investment you believe in and frequently buying it no matter what the price is.
That's generic suggestion we could read for so many times here if OP mean that.
Maybe better to think about other technical things that can help people on their investment since buying low and sell high is not easy as what they think to do.
I would maybe like if he suggest to buy and HODL since this is actually what ideal thing to do with our Bitcoins. Since thinking about those things will make them try to engage on bigger risk knowing market is so unpredictable.
