In my opinion, the game is interesting, but it would become even more interesting if users had more opportunities to predict the outcome of price movements. This can only be done by increasing the game timeframe. Indeed, 15 and 30 seconds are too short and the luck factor plays almost 100% here. If the timeframes were at least 1 hour, 6 hours, 1 day or even 1 week long, then the result would be more predictable and analysts, and not just entertainment lovers, would start playing this game. The color scheme of the site is also fun, but sometimes it can be annoying to the eyes.
