To be frank I don't think bitcoin is way too volatile as you said though we all can agree that it's volatile but not way too volatile, while time frame is limiting analysis, experience traders can make a strategy that will give them better chance of winning in their predictions
The platform caters to or targets two markets, traders and gamblers, this is like hitting two birds with one stone but both types of players have a chance to win but will also suffer losses because of how fast the game is being played, for you to have a positive result on this game you have to constantly check the market and get used on the time frame its a combination of luck and skills in possibly analyzing the market in a fast way.
Some of my friends played here but did not get positive results last time but they like the fun side of playing in this kind of game.
