That’s why most of us here are hodling bitcoin and spending fiat, because we know the fact that bitcoin could reach at its peak price in its most unexpected time. And because we don’t want to miss that chance, we prefer to keep bitcoin as a long term investment rather than to use it as a currency. However, I don’t see wrong with that as everyone here as it’s own time preference when to sell, but if we can also spend a portion of bitcoin to fulfill our needs, for me that’s not bad though as we opt to enjoy the fruit of what we had been working for long.

Actually, for conditions like this, I think it depends on you whether you really want to do something like this or not, because there are many people who do it now, although it's not uncommon for people to regret their assets, in this case bitcoin, to spend.
But I think I'll also be in the second bracket for now nor would I really intend to do something like that and would rather have paper or fiat money to spend over bitcoins. Even though it's like that eventually I too will do at least 1 or 2 times just to try to do the thing.

I am also in the same shoes right now. I know how bitcoin started from a scratch until it reaches its present market value that’s why i also intend to keep my bitcoin as much as I can until I’ll achieve my goal price. I don’t want to live regretting wishing if only I didn’t spend my bitcoin earlier. Good thing I still have enough fiat to spend for now, that’s giving me an advantage to focus on bitcoin as my long term investment, and maybe only spend when the price is right.

At first, yes I felt bad, but over the years of using it to buy things, I didn't felt it anymore. I'm not directly using Bitcoins to buy things online, but I'm converting it. I mean it's the same right since it started as a Bitcoin, and then converted it.

I felt bad when I used my own Bitcoins to buy my personal computer. I think I spent around 0.09 BTC at that time, but that was around 2019 when Bitcoin's price is still 4-digits. Fast forward to today, I'm not feeling bad anymore because if I didn't bought my computer at that time, I don't have anything to use now. It wasn't only personal computer that I bought using Bitcoins. I also bought a phone with it. I'm also getting some of my Bitcoins to pay some bills in our home (thru signature campaigns). Month after month after month, I'm using Bitcoins to buy or pay things (like I said, I'm not directly using Bitcoins, but I'm converting it).

Overall, it depends on the person who has Bitcoin. If he sees Bitcoin as an asset, and believe that it will go up in the future then just hold. On the other hand, if he sees Bitcoin as a currency that we must use to pay things then just use it because after all, Bitcoin is a currency at first. As for me, I see it as both an asset and a currency that's why I'm holding Bitcoins, and at the same time spending it.

I've never tried paying something using bitcoin because I know that it's a way of its potential at some point in the long run as of now. The profit you could gain versus fiat is incomparable, so I always prefer using fiat buying anything, less hassle and much cheaper in my opinion since bitcoin fee is gonna add up to the amount you're gonna pay for a certain product.

Paying with BTC is not bad option if you split btc into two parts. one parts for holding and other for spending via online transactions. unfortunately our country has not regulated Btc and crypto yet and there is no shops and service where we able to make payments through Btc.

Stable coin is Another good option for using online transactions that you mentioned because Btc price is not stable and for long term it can give you good profit if you hold tightly. By the way i am waiting to spend my first Btc transaction for online purchase and i hope our country Will adopt it soon.

For now of course, knowing that bitcoin's value will increase by 100k$ each, I feel honestly speaking it is really sad to make it an online payment.

      If I have cash to buy it for now, then maybe when I have accumulated a lot of bitcoin or depending on the situation, I may as well not use bitcoin as payment because of the value it has now.

What system in particular are you referring to? System of government?
That happened a long time ago; I guess that was the first practically presided Bitcoin usage. It wasn't Worth anything more than chips and pizza way Back,. I think that was also done to clear a pathway for the P2P Trnx process which enables a greater amount of scalability today.
It's not even advisable to sell off your coins for the fact that the market is bad or diminished greatly; it's even advisable to buy at that point so it would carry you along to it Apex. Sounds really weird but it's even weirder if you begin to sell now at a big lost.

also, do remember, if you are using your satoshis to your basic needs, then for me, that's not worthless. you can always replace your used satoshis but being hungry, you couldn't replace it. your health is more important than your satoshis.
so i don't feel bad if i am converting my btc to fiat to buy food or paying my monthly bills. you can always find ways how to acquire satoshis. don't let yourself go in deep debt because you don't want to spend your satoshis. better sleep in peace rather than be stressful from the people you owed money from.
