As always, the larger businesses grow, the less they start to care about their users. The only thing that matters for them is to book positive results with growth in mind, and that's being done by cutting on staff expenses, which is exactly what Coinbase seems to be doing right now, all to please their dear shareholders. Definitely expect this to become worse rather than less.
Binance must be laughing its socks off with how its closest competitors are screwing up badly in terms of staff allocation. People nowadays are specifically looking for exchanges with reponsive staff departments, and this is where you can seperate yourself from the rest as exchange. Binance is the only exchange who figured that out it seems.
Spot on! Examine the fall of every major exchange (looking most recently at Poloniex for example, who commanded huge volumes and had their loan facilities awash with requests), it all boils down to the inability of support staff to handle requests promptly and correctly. People love the basic features - low fees, yeah, liquidity yeah, fast execution, great. But when something goes wrong, you really appreciate a quick response that aren't scripted and staff who actually pay attention to your details.
Which is why I've stuck to some smaller exchanges where I get that, and which is why I think Binance will go far - at least on the looks of it now, with them hiring staff even as their capacity is growing (though recent complaints appear to show cracks). Every new exchange asking for suggestions, this is what I always advise too. That's going to be the true differentiation - good old customer service.
