Well, first congratulation on your 1st max-win... But you need to have self-control mate.
You need to establish a budget, for example 300k IDR is your budget, so if you won 1million IDR, you should withdraw 1000k minus 300k = 700k and play only with 300k. That way there's no such thing as losing 600k in such a short time.
What if you lose the 300k? It's fine, you still have the 700k for the next two sessions for next week and the following week.. Remember.. NEXT WEEK

Thank you for your suggestion, this is really good point that i need to learn. today I've tried to control my self after got the rain from sweet bonanza, with 1Mn IDR profits, and withdraw it, just keep my 200 IDR initial, on my BK8 account. at least I got my losing money before, and will waiting for the next week payment, maybe I got some profits again
