Actually you need to trade something like a few ks worth of BTC over your entire account lifetime to recoup the fixed fee out of what you save on % fees.
So, trimming the bullshit from your post, we're left with this statement.
Lolwut? You need to trade "something like a few ks worth" to recoup a fee of ~$1050?

Where exactly is charging these mystical massive fees?
