Just while I finished reading the OP it in a way pricked me with the thought that sometimes it's a good thing to have to forget about certain valuable assets of ours somewhere to later recall about it in the future, for by then it would have grown in much value and a better gain for us. Because am very sure the man would have sold those mined BTC the very first period it grew in value to use the money to handle a pressing family needs as a husband without him thinking what the future of the asset could be today.

It reminds me of a thread in the forum that talks about how people should go dead on their bitcoin investment as it's one way to avoid FUD and panic,  so as to be able to reap great profit in the long term.
