Winning 7k with $1k is kinda basic if you ask me, most people do that with simple bets without using any form of strategy that are complex... it's just x7 and that's pretty much achievable with minimal effort..and considering the fact that you did this for 35 days makes if stressful but the only advantage to this is the minimal risk involved.. splitting your bets into weeks or months can increase the chances of winning..But this doesn't mean that luck isn't involved, you can do everything right and still end up losing.
