We had this discussion already a month or two ago. I think we've had this discussion more than once.

I suggest you ask BCX about how mining at a loss for many months paid off for him with BTC ($3 to $1200) and LTC (<$1 to $30).

Why not just buy the LTC? Because I think he already had the mining rigs. Sunk costs are free.

Also because exchanges are not convenient for everyone (5 ids, a blood sample, etc).
