Such high gas fee when you need to pay more than 10$ is not appropriate. Even transaction fees on Ethereum are lower sometimes. Actually, there are two factors that influence rising of gas fees. First of all, the price of BNB is growing. Secondly, when the activity is high, you have to pay more so that your transaction will be included in a chain. I am used to pay not more than 1$ on Binance Smart Chain, so I am really confused by your case. 
Day by day gas fees of BSC will be pump like ETH depend with how much price BNB coin later, last time when BNB still dump only reduce fee under 0.1$ and now need almost 1$ for swap coin on pancake or other dex exchange support with BSC. Right now only with Matic or polygon network have lower fees transaction for sending or swap coin and we got fast transaction.
