If you want to trade, use a derivatives powerhouse like binance. Trading crypto spot is mostly just a waste of time. Until Coinbase and Gemini add futures and swaps, no trading firm or individual is going to trade with them. Full stop.
Volume is much lower, the amount of leverage you can get is lower (I don't believe you can get any leverage actually on coimbase), and the kinds of strategies you can run are limited.
Futures and swaps just give you so many more contracts to arb and more leverage if you want it.
