This virus is not something to underplay as a "common cold". The death toll for this virus is beyond SARS at this point but we're not yet sure what the mortality rate is. SARS had a mortality rate of 11%, so far it's been estimated by WHO that covid-19 has a mortality rate of 3.4%, but if you ask me, it seems way higher than this...
“Globally, about 3.4% of reported COVID-19 cases have died. By comparison, seasonal flu generally kills far fewer than 1% of those infected.”
It also seems to be mutating according to some claims into deadlier strains, but this hasn't officially been proven yet. Were it to be true however, something that mutates that fast that severely has no cure. Period.
But if a virus kills it's hosts faster than it can spread, this eventually leads to the 'extinction' of the virus with careful measures in place.
