I don't have a problem with a few percent fee. Before I went into the market, I spent some time comparing differences and trying to find which would give me the best rates etc etc. In that timeframe, the BTC went up about 100%. So, if you're doing one-off purchases, I would not bother with a few percent more or less. The general volatility of the BTC is *way* larger than that anyway.

However, if you are going into bot-trading, doing several trades per second, then yeah maybe those fees matter.
