It's only true if people use their non custodial wallets for storing bitcoins and broadcasting their Bitcoin transactions. If they use centralized exchanges, the story is different and they will have to pay very expensive withdrawal fees.

Usually the standard is 1 sat/vbyte minimum but people can learn and take some technical steps to be able to broadcast their transactions with less than 1 sat/vbyte fee rate.

How to make a bitcoin transaction and pay less than 1 sat/vByte.

They can do that to enjoy cheaper transaction fees on Bitcoin blockchain with good security from this strong chain.

Bitcoin is really the best for me too but don't expect everyone's opinion to match ours, some people will still prefer to use transfer or debit card to make payments and to them these are faster options than Bitcoin.

To me bank system can't be entirely escaped from, to spend and use Fiat you will still use the bank in the end, I wish there is a way around this but that's if all merchants for goods and foods start accepting Bitcoin, but it's never happening in my country.

When it comes to the cost of making transactions I believe that bank is better here, I can't tell how many times my bank app has given free transactions for me to make, a part of promotion I guess and still, dollar rate wise, Bitcoin is costly than bank transfer.

Before knowing this, let's see what to do if we send money through a conventional bank. As a first step, we need to know all the information of the recipient bank account number and details. The bank from which the money will be sent will have to exchange his fiat money and then send the money to an intermediary bank through a bank in that country. That bank will again send the money to the account of the recipient bank account number. That is, when a sender is going to send money to another country, he has to wait for a few days after providing a lot of information.

But in the case of Bitcoin, there is no such problem. There is no need for any details of the sender or the recipient. According to his convenience, he can send his money at any time. Surely, such a facility is not possible through any other medium except Bitcoin. This facility of Bitcoin is now known to everyone worldwide. Moreover, Bitcoin is also the best in providing security to personal assets. It can provide maximum security for an individual's assets in any situation, whether it's a political conspiracy or something else.

I think the only time I would choose bitcoin as a preferred currency for transactions is when I am sending money outside the country or in other words, intercountry transactions because how fast and reliable and low cost one can use to complete transactions. But when it comes to intra - country transfers and operations, using Bitcoin is a huge drag because some businesses don't accept it as a medium of exchange hence the superiority of fiat system within the country especially mine.

So I won't say I choose Bitcoin for all transactions but depending on the situation I find myself

Finally, after so long I've read a post from someone who is actually happy and praising the use cases and functions that Bitcoin has got to offer, otherwise, most people are busy only talking about the market, the price of Bitcoin and other cryptocurrencies, when they should buy, when they should sell, whether it is the right time to buy or not, are we late into the party, and a bunch of other questions and topic only related to the monetary value of Bitcoin. I'm not saying there is anything wrong with that, but I'm just saying that even though Bitcoin was originally created for what OP has described here, it is still very hard to find people using it for these purposes nowadays.

The cross-borders transactions and the ability to send funds from one corner of the world to the other within a few minutes when there is no network congestion is definitely the best feature Bitcoin has, and it is rightly comparable with fiat and the traditional financial systems for how they handle cross-border transactions. It will literally take you so long to do that if you go through the banking channels, and you will be asked for a bunch of proof and whatever only to prove that its your own money and want to send it with consent.

Out of everything that you have said here, the part I appreciate the most is how conveniently Bitcoin has made borderless transactions easier. Those who use fiat for this purpose, especially when large transactions are involved, face restrictions and/or unnecessary verifications that can cause delays in the transaction process. Of course, I also appreciate Bitcoin's top security features, which help keep our bitcoin secure.

Aside from these points that I noted and appreciated, everything else you have written here is poorly researched, which is why it contains a lot of misinformation. Others have already pointed out that Bitcoin transactions are not free, along with other contradictions in your post.

However, if you only see Bitcoin as a fast payment method, I think its greatest strength is somewhat hidden. Actually the real value is that you have complete control over your money. You don't have to wait for a bank's permission or a specific time, this freedom is what sets Bitcoin apart.  However for small everyday payments, using the Lightning Network is now more realistic. On chain transactions are good for large amounts or final settlements but for small transactions, Lightning works much faster and cheaper. So for me the real strength of Bitcoin is not just that it is fast, but that you have the opportunity to use both on chain and Lightning options as needed.

He is just trying to promote Bitcoin I guess because if he is unaware of certain periods like when the Bitcoin network is clogged with images through Bitcoin ordinals that would cost transactions fee to be very high and it got so crazy that sometimes the fees that pop up up when you want to carry out a transaction gets bigger than even the money you want to send, although it's never a permanent issue and this sort of things happens rarely but the clear picture is that despite all Bitcoin is still a better financial system.

If Bitcoin is not really the best and most reliable, millions of people all over the globe won't be into it, to think of using it as a border payment.

Bitcoin is however, proven beyond all reasonable doubt to need no third party for its transactions to be complete. You can travel with it or be wherever you are to make a secure transaction without interruption/failures, and the beautiful thing is you can send or receive Bitcoin anonymously
