Since you are sending from a Blockchain.com wallet, the option of speeding up your transaction using RBF is not available to you. Who were you sending the coins to? The recipient could perform a CPFP transaction if you are in a hurry for the transaction to confirm, although this will incur a cost. If the transaction is not urgent, then just be patient.

Thanks for your fast and helpful support.
Actually, I wanted to convert some of my BTC to USD through an online exchanger. They gave me a wallet address for sending BTC. I sent them my BTC when it was $10.084! The problem is that BTC fell to $9600 today and my transaction has not been confirmed yet. This long waiting time made some losses for me. I placed my order at $10K but I don't know how much I will receive in my Perfect Money USD account. They should be really generous to calculate my conversion based on yesterday's exchange rates.
Maybe I'm lucky enough and at the time of confirmation, BTC rises again to $10K!

If it was a "traditional" exchange (not an on-the-fly-no-kyc-needed exchange) , usually, you get a deposit address, and as soon as a transaction funding this deposit address is confirmed, they let you trade at current market conditions...

This has it's upside: you can fund the address they generated for you with a tx with a 1 sat/byte fee, it doesn't matter if it takes days (or weeks) to confirm... However, if you chose a low fee and your transaction remains unconfirmed at the "perfect" trading time, you won't be able to make the trade.

Things are a bit different with those on-the-fly exchanges that don't require you to create an account, these exchanges usually give you a limited amount of time to fund the deposit address, but they usually do guarantee a certain exchange rate (albeit, it's usually higher than with the "traditional" exchanges)
