1.70-2.50 is quite big if you can win consistently but I'm sure you've experienced defeat so you shouldn't say sure match or what you mean by sure match is fixed match, and usually bookmakers will start to suspect accounts that can continue to win because that's something which is impossible, and usually fixed matches are only on small sporting events so bookmakers will be able to detect things like this easily, so when you say you have 8 years of experience in other post without problems it's quite strange and I doubt it.
Yes it's quite big of an odds but I have some reservations regarding that because it's too good to be true in my opinion, a consistent odds no matter and the chances of winning the bet is much higher, @blckhawk and @adultcrypto have some doubts with this post and it's a valid one because there's no way that there's nothing wrong with this one right? It's good that almost everyone in the thread's being suspicious and cautious about this post, I would be too because of how attracting the offer is, not to mention that it's also involving Telegram which we all know is a scammer's paradise.
