I used the coins to buy pci-e x1- pci-e x16 extenders.
My last GPU rig was built on 21 august 2012.
I am not going to build GPU rigs anymore.
I hoard most of the coins.
I used a small part of the coins to place preorders at BFL and bASIC.
If the ASICS are true and hash as promised I will order more.
Litecoins are a very viable alternative for GPU miners right now.. not sure about the future though.
However I do suspect the price to rise when all the GPU miners switch to litecoin in the future, of course the difficulty will ensue which is why it is a good time to switch.
