do you have brain??
think....
it's easy, for win only!
Ok so you deposit 0.0005
BTC on Up and you deposit 0.0005
BTC on Down, that means your capital is 0.001
BTCYou are expecting a win on either of the 2 bets so you lost 0.0005
BTC and how much will be returned to you by secondstrade for winning with 0.0005
BTC deposit? Are they going to return 0.012
BTC?

I'm not good in math but please help me out how can you profit from this

if UP WIN - revieve 0.0011..
If this will be not scam, can use big bet..
