I think that's not a good idea mate, but as they said nothing is imposible to the believer let's just say that you can live up to 100 years old or more, but nobody knows what will happen to the bitcoin currency before reaching 100 years. we do not know that maybe in next 50 years there is something new currency has come out and stronger and higher than the bitcoin currency that will cause the sinking of bitcoin prices. No one knows.
