OK
I would describe Bitcoin as a house, and this house is built quite large on a farm. And LTC, EOS, ... are just animals, trees, or whatever you think, and of course they all give meaning to a common home. Good or bad depends on each person's feelings, but I think such a house is wonderful.
Therefore, if the house is not safe or there is a disturbance, then the whole house will also feel insecure, so most of the residents of the house also experience panic. this is clearly seen when bitcoin undergoes a correction, it is immediately followed by most of the anna altcoins, and vice versa
