There are two main ways of making money with cryptocurrencies: mining and trading. Both of them require research and experience. In terms of mining, the user should choose a hardware that suits to his budget, to the coin requirements he/she wants to mine, the electricity costs, etc. If those numbers are not researched and calculated, mining will be ineffective. As of trading, it is like investing in perspective coins and waiting for their prices to grow. Again, detailed research is required here on the perspective coins to invest in 2018 (for example).
