Is using a bot feasible?
I'm not expecting automatic doubling of my money every second week, but what about a constant profit of 3-5% per month.
Taking into consideration the volatility of the altcoins, this should be mathematically achievable (trough martingale or some other system).
I don't know any profitable bot on trading.But I can recommend you a coin working on this, Coindash. It aims to become a good investment management tool for crypto currency .
Its alpha version is usable, you can download it from its official website.
