I can understand how easy this might look for you, plus you already made about 50% of your initial balance back which is great.
My current account balance is €5,060.79, initial deposit was €4,008 and €2,000 was withdrawn already.
So €3,000 out of €4,000 is 75% of the initial balance (and not 50%).
But it still took you around 100 bets, with so much money on the line, one small fluke/mistake could cost you your full balance. How can you be sure there isn't any horse manipulation some day and you end up losing all your balance for some mafia to make profit?
This is not a low-risk investment, this is a high risk investment, because you can return your capital within a week or definitely within a month if you bet a lot ... nonetheless as you can see I took several precautions to minimize risk which is partial withdrawals (so if I lose the capital I won't lose 100% of it), and secondly I am actually looking right now to stop this - you have to stop at certain point because if you would blindly bet against 100-150 horses/dogs - you would eventually get burned ... it could happen after a long time, but imagine I would have broken even and withdraw my "Deposit" and then on the next few bets lose the lot.
So for me it's time to stop. I am now going to send an email to BetInAsia asking for a withdrawal.
