claims by the competitors
Stop blaming stuff on "competitors".
Your site is buggy and does not offer clear public stats. That's what the people want.
I've received suspicious PM urging me to cashout while the website was on constant DDOS. I don't claim this is a ponzi or not but I noticed suspicious behaviour from some members that seem connected to another competitor that I will not name for now.
The site is buggy but I didn't notice anything wrong and been monitoring the profit/loss change bet by bet. All my cashout have been processed quickly and support answered back to me within 1hour several time.
