In my views, there are many ways to gain profit with cryptocurrencies where other people were interested into mining which cost a lot of capital particularly on the mining equipments that really cost a lot. Others are into trading but this requires good trading skills and experience to be able to come up with promising profit. The most common way is putting some investment on btc and altcoins provided that you should have the basic understanding and familiarization of the coins you wish to invest. Lastly, with no investment required, you may join the signature bounty campaign where you can earn stakes by finishing the required postings per week til the end of the ICO campaign sale.
