I've built a 15k BR from 2 buy-ins: $10 deposit on party - 5nl was the lowest stake. I wouldn't recommend to anyone to deposit more than the minimum. The vast majority of players will end up loosing money one way or the other. The less you put online the less you're risking to loose. There's about a 95%+ chance that you're going to dump those $100 to either the rake or at a higher stake along with your profit.
