Thats valid but most people call valid after get confirmation at least 1 confirmation.
Isn't the case that you can speed things up by increasing the fees you pay.
Or am I mistaking.
Yes you can have your transaction be confirmed faster by paying a higher transaction fee compared to others so that miners will pick up your transaction first among others. During the time when network is congested, people would want their transaction to be confirmed faster so they would pay a higher fee until such time when the average fee would go higher. To avoid paying a high fee, you should just not transact bitcoin during this time if you don't have urgent needs for it or convert to other coins like ethereum or litecoin if you want to send one. Check in this site the recommended fee.
