What I mean by certain times is hours, days or even weekends to make each transaction in order to get less fees as stated by @blackboss.
I didn't understand before and in my previous opinion it was clearly written if I asked whether it was true that different times determined the transaction fees were true and real.
If you are using Bitcoin, you can still get slightly lower fees on the weekend, but like I mentioned earlier, Ordinals have pretty much made the cheapest of BTC transactions impossible nowadays. Right now, we have close to 50k of unconfirmed transactions. It wasn't uncommon that this number was down to 1-3k a few months ago, but not anymore. But if you are using alternative chains that have cheaper fees and quicker block times anyways, I wouldn't concern myself about the time you make your transaction.
