Massively so. Gox wasn't far off the entire market. We had BTC-E, stamp, gox. Probably some smaller players that I'm forgetting but whatever. Oh, and there was basically only BTC and LTC. Other coins either didn't exist or were just traded for each other, very little value, etc. When Gox went under there wasn't even really a proper market price for Bitcoin for a significant period. We had goxbucks and goxbtc. Even if Coinbase went down now it'd be less of a big deal than Gox was back in the day.
