I've got a hundred USD which I wanna invest in some altcoin. I know this amount is nothing, but since I'm a complete noob at cryptocurrensies, I decided to begin with the small amount. So, I want to try out how everything works, at the same time I want to keep my investment safe and sound. That's why I'm looking for some underappreciated altcoin with the bright future which will graciously accept my modest investment and bring me it back with some profit
Have you heard anything about this kind of coin?
Unfortunately there is no such thing as a "safe and sound" altcoin investment. Cryptocurrency investments are EXTREMELY risky and highly volatile.
