A lot of 1$ SNGs

Last week I started coaching some of my friends. We started playing some $1 MTT SNGs (45 and 90-man) @FTP. I had $100 in my account and they started with $30. After several tourneys all of them made a nice profit of over $10. However, I'm again at the red line losing half of my bankroll... ahahahaha I also played MTTs from $5 to $10, investing everything i won at SNGs... and little more xD. I hope we're gonna hit the 50 tourneys point till 21st this month and I'll post a graph with our results.
