Bitcoin high transaction fee? No. Maybe you are using exchanges which have higher withdrawal fee or unreputed wallet using high fee estimation. Bitcoin network transaction fee depends how on congested the mempool is, but mempool has been far less congested than congested in history, even far less is an understatement become it is far far less.
The mempool is usually congested when there is a bull run and market reaches a new ATH. I have once made a transaction and it took close to a full day for the transaction to be confirmed on the blockchain.
Although I will say it was a result of the mistake I made because I chose the least fee instead of the medium or priority fee so that was what led to my transaction being delayed for a long time and also it was during a time when the market was bullish so it was very congested and transactions were very slow especially for those who made use of low fees. For this kind of situation, the best thing to do is to wait for a better time when they fee is not high to make the transaction.
