well if you seek profit "right now", start trading.
mining is "future" profit, if you choose the right coin, just like it was when BTC started and only few ppl knew about it.
there is no big profit in mining BTC anymore, you can do bigger profit by trading BTC.
keep in mind that lower the ZRC network hashpower is, bigger daily rewards you get.
there is a bright future of ZRC ahead, you need to stack up a lot of ZRC for it
