Mining is an activity related to the return on investment (ROI[1]) over the long term, meaning that you will look for times when the currency is not profitable and you expect that it will rise in the future, which will turn your profits from $20 a month to $2000.
Currently, mining is not profitable. For example, if you have a 10 terabytes, the value of the coins collected from a 10 terabyte plotting will be within a dollar per day, which is a very small profit and may take a long time to pay the expenses.
All profit will be increased in value, which is not guaranteed and a high risk.
