> ~50% wont even show any symptoms

It is closer to 20% A lot of articles stating more are mis-interpreting those numbers from prospective studies. It is possible that the authors of such studies would downplay false positives as well.

50% keeps recurring because multiple mass testing efforts found that half of tested people were asymptomatic. However, that is mostly a function of a long incubation period. A significant portion of the infected developed symptoms later.

I think they don't know yet, even the US were saying it might be 25-50% a couple of days ago. For example the testing of the aircraft carrier, one of the few cases of total population testing, showed 60% asymptomatic cases but had a young population, and it's not clear from the information we've heard publically if some of those will develop symptoms later.

So at the moment no-one really knows for certain.

60% asymptomatic at the time of testing

Most of them will eventually begin showing symptoms
