Did anyone use Dexsport.io. What do u think about it? I have a few friends who used it and withdrew about 800 dollars, but TrustPilot reviews scare me as fuck. 
Where did you find this gambling site? If you find them here then there is likelihood that few people could have come across it then to know if that site is that legitimate or not. Most times friends sharing you their site they used to gamble could be very dangerous if only you senses those site as not trusted.
To be frank, I have never used this site and I don't also know about them for any reason.
