You are right, sincerely I have been playing Coinflip a lot, however mining seems to me to be very well thought out by Betfury, I think that this model is very well managed to be able to enjoy the platform much more.
If the funds deposited to the player's account also generate income through mining, it is very interesting how much interest per year can be obtained through such mining? Perhaps this is even more than in many deposit accounts. Then it is definitely interesting to users. How much can you get into your account in this way, who knows?
