How can I import first gen wallet into the latest release? I remember hearing there were problems sometimes. I don't have a seed, just a key file.
If you have a .siakey file to load, the method is going either to the Terminal and typing the command "siac wallet load siag

Not interesting at all, not sure why anyone would think otherwise. You need a computer running 24/24 + bandwidth + electricity + time configuring it + maintenance (tons of reasons why yo need to look after it).
I wouldnt do it for twice that price.
