I used to mine back in late 2013, 2014, and what I found is that it could be a waste of time and extreme effort, because putting all the money spent on the equipment into a promising coin, can give you much, much, much more return. But were in a different era now, so I suggest doing a little mining, and investing.
Exploiting and investing are all very good ways to earn income in this market and investors can fully participate. Tapping is a very good investment because you only need to invest in mining machines then choose good and potential coins to dig. As for investment, you need more knowledge of finance and market to succeed.
