Why are some people asymptomatic to the covid-19 virus?

maybe they lack the protein that the virus attaches themselves to
maybe their immune-system already knows how to attack this virus because it dealt with a similar one earlier

It is something called a sub-acute infection. That is the person is infected with the pathogen, in this case a virus, but the person shows no symptoms. This is usually because their immune system mounts a response which keeps the virus under control and does not produce symptoms. Immunology is not my field but I suspect it is a very moderate response to the virus as many of the symptoms are the result of the immune system's response to the pathogen and are not directly caused by the pathogen.

Younger heaIthy immune systems wiII generaIIy keep the virus in tact, preventing it from causing pneumonia and other compIications. Older and Iess heaIthy immune systems won't be abIe to fight off the virus fast enough, and the virus infects more ceIIs aIong the respiratory tract causing coughing, sore throat, loss of smeII and taste, fever, pain around the Iungs, and breathing probIems.
