Wishing your father a speedy recovery, sickness isn't something we should be joking with and we have to be prepared at all time as we don't know what is going to happen to us that'll make us not bee able to make money again and we have to rely on the money that we have made before we got sick. Having different investment and not only Bitcoin is a good way to plan for our future and we also have to get sold plans on how our assets are going to be managed when we're not here anymore or have some health issues. Not having all our money in one assets through trading or investing will help us or any individual managing our assets when we're no more.
