Bitcoin is having this problem and that's one of the reasons I don't want the price of bitcoin to high like too much like it did in 2017. The fees become very high when the prices goes up too much. Just recently that the price managed to reach about $8000+ plus, the fees started to get high. That is unlike other cryptocurrencies cause they are not like that, their fees don't get that high when they increase price (or maybe they are like that, but I don't know). But people wouldn't leave bitcoin no matter how high the transactions fees get, just because bitcoin is the number one cryptocurrency in the market, lol.
This is what the lightning network wants to resolve. Maybe in the future, the usage of LN will be more popular to crypto users and merchants. Right now, they are already addressing the high fees involved in bitcoin transactions. It is only a matter of time of adopting this LN technology. So yes, the possibility of having low tx fees is more than possible.
