I guess that's how it is going to work, OP will convince us that he do really have a friend who is playing CSGO professionally, and this whole story is just some random shit just to scam people to earn easy money to all of the people that will believe in this story. I'm pretty sure that most of the people that are going to be scammed by this post are those Newbie ones, like you, but I'm not blaming you though, because we've been in the same stuff the first time I entered this Cryptocurrency World.
But, this will take as a lesson to you for sure, at least you knew that before you send first, you have to think first if the post here is legit or not, Proof first before sending bitcoin.
I've been thinking the same after re-reading the recent posts in this thread. So in short this betting is all about a player which is your friend would play in a team tournament, and you recruit us and let us invest or bet on the enemy side and in the other half that friend of yours would throw the game so we will win the bet? Right? I'm curious enough, if you say so that he is a professional player, it is also possible that this is in the official sports betting site right? then why would he throw a professional scene for just a $500? next is, do you really understand what you are doing? if he's professional then he's aware on how the rules would he violate right? do you even know that once that you are proved to be throwing a match you would be ban from valve sponsored games?
I do hope that you are not lying on us, since there would be no stupid enough to throw a game if possible and most of all its a PRO scene, if its not in PRO scene or not listed in some E-sports event then i wont bother betting honestly.
