You should not worry about that as you (and all of us) will be long gone by 2140.
I agree

. I can only predict a situation few years from now but not after a hundred years so let's not really worry about it. Everything is still unsure about crypto currencies even after 10 years as we don't know what will happen then. There will be factors that will surely affect coins in the future so let's just pray hard that everything will be a great advantage for us.
