Hey mate, welcome to the endless roulette struggle haha! Martingale can work short term if you have deep pockets but one bad streak and you're toast, trust me I've been there. Better stick to European wheels (single zero) for lower house edge. For strategies, try D'Alembert or Fibonacci - less aggressive, more sustainable fun. Also focus on sites with high RTP tables and decent bonuses to stretch your bankroll. Oh and check out
Finestonlinegambling.com they've got solid reviews on top roulette casinos with live dealers and good promos. Helped me pick a reliable one last month. Good luck, don't chase losses!
