Every coin(including Bitcoin) was starting at the price of few cents. I know some investors are focusing only on coins under 1 dollar.
If we're talking about trading (rather than long term investments), then ignore what the likes of BTC have done - sounds odd, but that's an anomaly. Buying a coin with $0.05, then selling for $0.5 is great business.
Coins under $ 1 are a great opportunity for many investors to find potential coins in the future because you do not need a lot of money to buy these coins but the possibility Very strong increase. I also invested in XRP and DGB in 2017 and I felt good when both of them had a strong time.
