If you started mining with ~10 HD5870's in 2011 and kept doing just that and you kept most of the BTC you are perfectly fine to spend your free money on these 60% chance scams.
But for the avarage joe like us we just can't spend 10K on something we don't even know if it wil ever come...
Yea this is basically how I feel. I mined with just a GPU back in the day and after a few weeks finally got 1 BTC, then I sold it when the price skyrocketed to 270 xD
Now I really just want some BTC for the vanity and to play some of those betting games, but don't really want to spend too much money on it as in a few months whatever hardware I buy will be outdated and close to useless
