if you give 7ltc of 50 ltc from block and your fee is :
Our Current Fee is 0%
that means that you are giving less to rest of miners or you are in - if you want to make pool alive better to give bounty of 1ltc or something to all new miners that have min 1.5 mh/s hash rate power ... or more hash rate power more bounty...
many of alt coins are made from old bitcoin miner (GPU Miners) so they can survive ...point of bitcoin is many people involved not everyone has asic so i think that there is good there is alt valute like Litecoin(scrypt coin),if some Coin want to survive there are not enough only miners and some valute..it must has USE...bitcoin has use and everything so he will survive many other altcoins dosent in few months.
