This method works with only 3$ or we can try with lower amount also?
It worked for every amount. I just said you need to put just a minimum amount, so that if you loose them, it will not hurt you. You can use 1$ or 2$ or 10$ or 1 btc. i know one of my friend use to send 1 btc every day and he won almost 40 btc.
Cool, What if they read this thread
