Comparative table on fees among some coins. Pick up one for your need.

The same could happen with any of the altcoins that currently has low fees, except for the ones with truly large blocks, but coins with megablocks are so centralized that they can't really be considered cryptocurrencies - they are not peer-to-peer, they are client-server.

actually history has shown that those altcoins with bigger blocks would have higher fees just as easily without even having their blocks full. all it takes is a small rise in the number of unconfirmed transactions for the fee to start rising.
why?
because they are copies of bitcoin and they are copied by incompetent developers who have very little understanding of the code and bitcoin protocol. for example bcash that has 32 MB blocks creates a fee market with a small tx surge while miners continue mining only 1 MB blocks!

I notice there are a few hours window where you can send BTC rather cheaply, it's about mid-day Indonesian (GMT+7) time, not sure whether it's coincidental or not, but I managed to do it multiple times with less than $1 fees mostly and got confirmation in the next block or block after that.

It's definitely a recurring pattern.

Have a look at https://jochen-hoenicke.de/queue/#0,6m, and zoom in on any 7 day period from the past 6 months (or longer). Outside of times when the mempool is backed up for several days, it generally empties or at least dips to the lowest around the hours of 0200 to 0600 UTC, which coincides with midday in your time.
