Personally my best investment currency btc and eth i think my first profitable ways buy sale person to person in my country. Basically bitcoin always king number one of the best currency with good profitable if you take investment in right time.
Yeah Agree with you that bitcoin is the king coin and we use to call bitcoin as mother of other altcoins. Bitcoin is best one and it will be there is everyone's portfolio but after Bitcoin the only coin I trust the most is ETH as both of them has good growing ability and it has power to rise in price. That’s why my choice is BTC, ETH, and Ripple.
