i think you explained it in weird way and your English is a little broken but it is an interesting comparison! in a "bull fight" (https://en.wikipedia.org/wiki/Bullfighting) the idea is to have fun with bull that runs at you lol. if you have no idea what you are doing you will be dead under its hooves or end up with a bull horn in your belly!

it is the same in the market. you see the "bull run" and prices that are shooting up but if you have no idea how to handle it you will be crushed under the "hooves" of other traders. specially if you are trading pump and dump altcoins you will be crushed under the "hooves" of pumpers as they take a dump on you....
