The concept is very addictive and you need large funds and a good focus because there is no time out the game is continuous 24/7 I will not be surprised if some players play for hours here.
I don't really get what you meant with a large funds since minimum deposit is 5 matic which is quite similar with other platform offering this while in order to constantly make predictions you may need more funds, the core thing here is the focus because no matter the amount/time you are predicting if you're not focus but just randomly predict you may likely end up losing except if you're good with guessing.
It's not the bet, I may used the wrong word but bankroll as I don't think a few bets will not give you positive results on your bets for you to fully grasp the game you need funds that will run for several bets because it's a fast pace game, I agree the main element here is guessing, because even if you are in front of a graph you still cannot figure it out, but if you know the market sentiment you can use that to your advantage.
