I am sceptical of all this fixed matches. If they are real, the person won't be selling their tips and would bet directly.
Many of them put up fake screenshot of past winnings. When they cheat enough people of their money, they will disappear.
unfortunatly, more time is true, expecially in italy, because already if a player fixed match, don't go in jail and more old player, for monetize the end of carreer, fix match
