Honestly I fail to understand what even the point of this betting system, considering how crazy limited what you even can buy in that shop. One seal fragment daily? This is serious? After I exchanged all my *, I ended up with 270.000+ chips. And I dont even think that would be that much, I am sure many more gotten even more. Considering you keep getting more and more materials what you can exchange, I could keep spending it without any need to bet.
So at this point, I just really hope, or suggest to increase the limit in that shop, or put more stuff to it, because sitting on 360.000 survival coin is already * enough, dont really feel like gathering chips too for no reason, because oasgames are holding back every kind of free ninja from the shops or putting everything in group shop, what we have the lowest possible means to get coins.
