I do not think it's true for bitcoin miners to see that bitcoin is currently decreasing if you do mining, then what you are struggling will not match what you get. My advice if you want to do mining then it is better if you choose a better altcoin and more dominant in price issues. Because mine requires patience and persistence so that everything can be smooth.
Add up to this statement that mining needs a higher GPU to get a higher security and prevents to break the codes. It is need to notice every time when it reaches the limit of certain coins.
