I am mostly interested in the smaller cryptos. More specifically, my aim would be to have a robust trading method for Hive, Hbd and some of the big guys. I am not sure how BTC/USD affects crypto-economies within crypto so I was thinking of restricting everything to crypto. But I am absolutely new to trading cryptos so I am not sure what I am doing.

Yes, pricing in crypto is the way to go, but the readers will be better able to understand the price in dollars.
I'm still for both.
