Hi,
I have a 0.1 BTC paper wallet that has not been touched since 2015, I don't know if it is any more valuable since its untouched ? Some one might want to offer some more for it, I don't know ?
If its untouched then it doesn't mean that it would lose its value.Just like been suggested above its better to hold of those coins little more longer which it can potentially rise up even more. No one would really pay up more than on the value as of now.People can easily buy up on exchanges on exact rates than on buying to someone with higher rates.Instead of selling it better to add it up since price of bitcoin is lower as of these days.
