Some say cryptocurrency is a low risk investment but high return and also does this digital currency have a fundamental value so that it is feasible for investment?
What do you think ?
All investments you do always involves risks. Whether how small or big it is, it's still a risk. You should always do your research. Focus on altcoin projects with real utility and good fundamentals.
I can suggest one very good project - Stakenet with its native currency XSN. It aims to make every transaction fast, smooth, scalable, almost fee less and virtually secured over the Lightning Network and Connext. Please check it out.
