Is it true that there are certain times that provide lower transaction fees?
All this time I did not know about this because when making each transaction I did not really pay attention to the fees I had to pay.
After all, I am a small gambler, so every transaction I make is never with a large enough nominal amount so that the costs I need to pay are relatively low.
If indeed this is real, maybe it can be a reference for me later if one day I get a big win and want to withdraw all of my winnings so I can save on transaction fees.
I am not sure what you mean exactly when you say "times". Do you mean part of the day, like in the morning or evening? Or part of the week (business days, weekends)?
Since Ordinals got introduced to Bitcoin, it doesn't matter when you make you transaction. The network is constantly congested. It's become even worse because what used to be 20-30k of unconfirmed transactions, is now 50-60k.
If you are talking about withdrawal fees on casinos and sportbooks, it is especially important that you pay attention to that if you are a small-time gambler. Small wagers equals small wins most of the time. If there is a hefty fee when you withdraw, that win becomes even smaller.
