DASH VS BTC MINING

So the other day is started mining for the first time ever .... and i have come to notice that mining dash is very different compared to mining btc , mining dash is very hard because getting one satoshi takes longer than getting a btc satoshi plus x11 hash is very expensive am staring to doubt the profitability of dash

i paid 78 usd for the x11 and that was a discounted price

at the end of the contract i would have made 25 usd worth of dash . can somebody please explain to me what is the best way to mine dash that in the long run my account remain profitable
