As Bitcoin rewards for miners keep decreasing over time with the halving after every 4 years, I believe what will keep miners active still doing their job on the Bitcoin network is if they're benefiting from the transaction fees, and which is what we are currently experiencing lately, This to me looked like Bitcoin was designed this way on the long run to keep miners active in the system, Who knows we might even see more higher fees in the future when the rewards miners get from mining Bitcoin get lesser and this is for them to cover the money they spend in electricity bills

There are many options that have been mentioned and I basically agree that they can help. Expensive transaction fees are a problem in the bitcoin network currently, but over time transaction fees will decrease even though it is difficult to expect 1 sat/vB like before.

I agree that, if you have a steady income at a real job and the amount can cover your daily to monthly needs, then there is no reason to sell bitcoin now. You can accumulate your typical campaign earnings each week as a long-term investment, while still being able to sell a percentage of it when you need more budget in the lean months.

It's all "part of the plan". With high network fees, people will be forced to leave their coins on exchanges or centralized services. If this keeps up, only the wealthy (whales, institutional investment companies, governments, etc) will be able to practice self-custody of BTC. Fees may've declined now, but it won't last forever. Especially if the Ordinals craze continues. Core devs are reluctant to introduce network changes that would help mitigate the issue. They want us to switch to the centralized Lightning Network that's flawed by design.

I wonder how high network fees will be by the next block reward halving? Probably within the "four figures"? At least, we have plenty of other decentralized alternatives to choose from. Litecoin is one of them. At this point, we could say Bitcoin failed as a digital currency. It's only good as a store of value. You can rely on BTC as a Gold alternative, while using LTC for day-to-day payments (like Fiat). The future can't be predicted, so lets hope for the best.

usually it costs relatively cheap to DCA, bitcoin fee isn't as high as ethereum in the past, but due to the presence of BRC20 and runes, it does increase.
my only solution is only to take advantage of DCA through exchange, even though many people consider exchange to be rather risky when saving money since we got that flashback of FTX making people unable to withdraw but DCA ing could only be done effectively through that since the high transaction fee aren't going anywhere.
but honestly we can wait it out until the hypes about runes subsides first, so many runes minting these days, it does increase fee as high as $100 which honestly is ridiculous.

Exactly. It's best to make transactions at different time periods to save money. Keeping a few BTC on exchanges seems to be the only option right now. You can do DCA on a centralized exchange without the need to pay high network fees (except when you make a withdrawal). I've read that some exchanges are integrating LN support (Bitstamp, Coinbase), so high fees would only be a thing of the past.

Remember, patience is a virtue. Those who manage to wait, will eventually be rewarded in the long run. Bitcoin network fees won't stay high forever, anyways. I'm hoping the Ordinals hype comes to an end, so Bitcoin can be used more throughly as a currency than a store of value. At least, that's the dream.

There are actually viable options on which you could really be able to make use on which its true that when it comes to exchangers or on the time that you do have funds stacked into your exchange wallet then
it wont really be that a hindrance for you to have that kind of DCA thing not unless if you do make out some transfers from your non custodial wallet then it would really be something that will really be giving out that kind of hindrance just because you cant really be able to avoid that paying up that huge fees on which it do really sucks when it comes to that manner but we do know that not all the time that the fees would really be on the rooftop on which it would really be just that so common that you would really be letting the network to cooldown or would really be able to normalize because not all the time we would really be something like  this on which if there's that kind of spam in the network then it would really be taking up a couple of days or weeks for it to normalize. You could always skip out on making such move if you do really tend to save up with fees
but if you are really that eager on making such move then it would really be your choice.
