I am just wondering, if I invest in a bankroll, how long does it usually take to recover 2% dilution fee? I invested yesterday and I am deeply in red.
Like RHavar said, it will take a bit and I wouldnt check my stats daily. It will drive you crazy and make you worry! I speak from experience

Just invest, dont forget about it and check every couple of weeks.
You should be in this for the long run
