On the binary options casino game is the BTC price from Binance?
edit: Found it. Top right> user settings> odds format. The link to settings would be more visible if it were in the left list. It is annoying that it does not save preferences upon logging out. It appears I have to manually change to decimal odds every login. Also, the typos do not grant much confidence for a first time visitor. For example upon login:
Default odds format vary based on the user location. When the user changes the default option, a local config is saved in user's browser and that option should keep persistent for future visits.
Are you experiencing this return to default option (american odds) on the same browser / device? Or checking from multiple places (mobile, computer, etc)?
Regarding the second question of the binary prices source, we use an independent 3rd party api for realtime financial data (www.live-rates.com), and not a single crypto exchange.
Regarding the typos, it will be fixed on the next deploy. If you have noticed other typos please let us know!
