The first blow I took in crypto was by entering a coin because "everyone was getting in." I neither read, nor looked at the chart, nor knew what it was for.
I learned that you can't go in like a donkey with blinders. If you don't know what you're buying, you're not investing: you're throwing money down the well, like the water from the pitcher when the jug breaks.
Advice: if you don't understand the play, not even if your cousin from the cooperative tells you.
