Building Dapp like pooltogether

Hi guys
I am a software dev and I am thinking about the problems that I will have if I want to create a Dapp like PoolTogether.
The fees for make transactions on eth blockchain are so big that it is quite impossible to create a Dapp like that because I want to build a non loss lottery so I have to pay those fees and now the fees are like 20$… it is unsustainable to do that.
What do you thing about this? Is there another way to do this Dapp nowadays?
