I have some private keys created in a very old version of multibit (no recovery words ever selected/made). I can't seem to import private keys into multibit without having recovery words. And when I try to import them into blockchain, I'm unable to see the imported addresses (I did direct import) and amount associated with each address. What should I do?
EDIT: the money in my wallet from before is there, but I can't see any information about individual addresses (as far as I can see, only the multibit address appears to exist).
I have a dedicated single computer running 24/7 and here's it's specs: -450 watt PSU -AMD Sempron 145 CPU -ATI 5850 graphics card -1 GB ddr2 RAM -windows xp x32 -16 GB solid state drive -$45 micro-atx mobo
Basically I just got a graphics card with a cheap motherboard and CPU, but already had everything else in my spare parts bin. It currently gets about 300 mh/s, and I may eventually consider adding a second graphics card via a pcie 1 to pcie 16 adapter.
The price will likely increase with an increase in the difficulty to mine. Bitcoin has been constantly deflating as a result of the difficulty. Two bitcoins in todays market would've been like 20000 at one time.
