There are things to consider if you want to make profit by mining cryptocurrencies. First, how much money are you willing to spend for this? if you only have average amount of capital to start then I recommend mining with cryptocurrency that can be mined using GPUs (like Ethereum and Litecoin), if you have big capital and can afford to invest on latest ASIC miners that can produce huge amount of hashing power then go for Bitcoin. Also consider the price of electricity in your area, the more cheaper the more profit you will get (but still depends on how efficient your mining hardware is). Use mining calculator so that you will know how much you will earn each month.
