The value of it's gone up about twenty times since I bought it, back in the eighties.
That's quite a return. I live in urban area, and I don't have lot of storage space or any knowledge about wood really, so I guess it's not for me, but kudos on your investment decisions so far (both wood and btc

EDIT: just out of interest: is it hard to find a buyer/seller at a good price? What is the typical "spread"/cost of transaction so to speak?
