Yea I know. Some of them are even doing negative fees for maker. But does it matter if its -0.05% for taker and +0.20% for maker or 0.075% for maker and taker? Not really. Sometimes you will me maker sometimes you will be taker so on binance you have 0.15% for buy and sell and on hotbit you have 0.15% (once as taker once as maker). Same? not really because look at this:
LTC/BTC on binance(bad big exchange) and hotbit (small exchange)
0.025% vs 0.25% spread. Things are getting worse and worse on smaller exchanges and smaller coins.
You should also add into account that it is far more risky to have coins on small exchanges (weaker hack protections, exit scam more possible). There is nothing better right now for small and big trader than binance.
