Hate to bump my own thread, but the money is still just sitting there.
You should advertise it in the local newspapers

I would be happy to go to a trip to the location but to get there and to get home would cost much more than the value of the bitcoins in the wallet (maybe if the price of bitcoin will rise again around $20.000 there would be more interest finding that wallet...)
Yes, not really profitable to do that.

However, I will not be moving this for a year. If the price goes to $40K the game is still on. It would be funny if the price did skyrocket and someone got a free vacation to Africa. But even if it goes to a million... So be it.
