In the art of mining,there are two parts for you to make profit: 1.wage and 2. growth in value of the coin due to the growth in the network.
For any mature network,what the miner earn is majorly the wage.Luckily enough for you to buy a McDonalds meal a day for a small miner.
What the real money play is the natural increase in coin value due to the growth of the network.If Bitcoin Minor can attain this result(i.e. grew 9000 times after it launched a few day) just by a small number of people knowing about it,what will happen when 100,000 or even 1,000,000 times more people knowing about it? How many people know about Bitcoin Cash now? How many people know about Bitcoin Minor now? What happen if 1/5 of people knowing about Bitcoin Cash also know about Bitcoin Minor? What will be the coin price of Bitcoin Minor at that time? You do the Maths. A obvious super star is rising like rocket and everyone paticipated in the netwrok witness about it in the last few day. I do not want to waste my words to convince you anymore. The choice is up to you.
Well, the short period of growth shows that a lot of people are starting to pay attention, and the important thing is to keep going, any coin will take a long time to accumulate.
