I'm new about mining coins, but i just start mining alt coins. And i think better you save it and wait, because it's have a change that coin's price can increase.
Its good to get your feet wet.
Know the "estimated" coin able to mine and the actual #`s, since usually the miners "promote" how much "hashes".
But usually underperform but a certain # so take the real #`s or ask this before you purchase. So you actually get the exact #`s.
Just know those alt coins you mine, is a either a hit or miss that it will go up or not.
