From what I have experienced in any casino including casinopunk which I played some time ago. betting at $0.2 either when getting a free spin bonus or buying it never gets a profit above $10. Either I'm unlucky or the provider I play is not that good. Usually the PragmaticPlay provider is my favorite but in the future maybe I need to move around a bit to try whether $0.2 from buy spin exceeds $ 10 or not.
Well, my experience in any online crypto casino, is the opposite of yours. I'm not saying that I always won or hit a big multiplier, but I also don't win only $10 every time that I use a free spin or a buying a bonus feature. The biggest hit that I recalled with a $0.20 bet was in Pragmatic games and it was around $256. I guess that either you need to change a game or probably focus on one and see how far you will go. Ofc you can try other providers like Hacksaw and NoLimits, but from my experience, both of them need more bankroll than Pragmatic to get something big.
Yes, it does have to be more capital to get free spins because if a little is deposited it feels less satisfied, but good wins in the Ducks Hunters game get a pretty decent multiplier, it's just that when moving to this pragmatic provider it is difficult to get good wins, maybe it's not the time to be lucky. Lol
But I myself for slot games only need capital from a $10 deposit so I only enjoy the game briefly.
