I have noticed that the transaction fee has gone up tremendously during the last two weeks. I am using Blockchain.com wallet, and until two weeks back I was paying somewhere between 1-3 Satoshi per byte for my transactions. But now the default fee in Blockchain.com has increased by more than 10 times, to around 40 Satoshis per byte. And I checked bitcoinfees.earn.com as well, and according to it, the fee needed for instant confirmation is around 220 Satoshi/byte.
That blockchain.com's wallet is the problem which always estimates wrong fees. I don't know why their silly devs can't fix this. Use Electrum, even though the network is congested, I pay nominal fees. Or you should cross check with the fees estimator to see how much is the current fee per sats to get faster confirmations. I'd still be cheaper than blockchain.com's estimations.
I am not saying that at current levels this fee is unaffordable. But what if there is another 10x increase in the transaction fee? Are you willing to pay 2,000 Sat/byte for instant confirmations?
The network congestion cannot be controlled right? Unfortunately, bitcoin wasn't developed to solve this problem particularly.
