Re: 🚀 500xBit.com - Easily Bet On Bitcoin - 500 ❌ 250 ❌ 100 ❌ 50 ❌ Insane Leverage!
I mean using some special offers for us members, not available anywhere else.
There's this: 🚀 [FREE TO ENTER] Predict The Bitcoin Price - 250$ in prizes🚀Until Sunday 9pm 
It's nice that they have something like this kind of games and rounds promotion but I think in order not to be abused they should at least ask users to place at least 1 bet and use the ID as a ticket in order to place prediction on their promotion, I think that's a good idea to control users with multiple account.
