In the past I thought it would come one day, in the very distant future, but today I think there will never be a day-to-day use of bitcoin, as it is too valuable to meet everyday expenses with it. I see it as plausible that a kind of bitcoin standard may come in the future, as fiat currencies are devalued and bitcoin continues to appreciate while becoming increasingly scarce. But there are too many possible means of payment to stick to just one. Normally, people tend to save bitcoin and use it for large or at least medium-sized payments, and for day-to-day payments use some junk.

I think it's completely pointless to even talk about BTC one day becoming "a common method for daily transactions" because if people haven't accepted it that way after 15 years of existence, I sincerely doubt that it can ever happen.

I think the turning point was 2017 when BTC actually hit the mainstream media as a super profitable investment, and then the idea of ​​cryptocurrency slowly started to fade, especially when Microstrategy appeared, and then later BTC spot ETFs. Although there are thousands of online stores that accept BTC, it's enough to look at the mempool and it's quite clear that the number of transactions is at a record low, which just means that 99% of people are just holding and waiting for the right moment to sell.

I'm surprised that some older forum members (like the OP) are asking these questions, because by now they should have learned that Bitcoin was created as an alternative to the existing financial system, not as a replacement. How many people own BTC today is difficult to say, but it is probably less than 5% of the total population of this planet - so a much more meaningful question would be when we will reach 10% of those who will own BTC at all.

If I am to be very honest, I do not see Bitcoin now or in the future being used as an everyday currency. Not that it is not possible, but Bitcoin enthusiasts see Bitcoin more as digital gold. In the near future, as the value of Bitcoin keeps increasing, the digital gold mentality will fill the minds of many. They would rather invest in Bitcoin for more returns than spend it on bills.

To even think of it, the increase in transaction fees and volatility really makes Bitcoin unsuitable for everyday use.

If we are talking about adoption generally, we are almost getting there. Although, when people think of Bitcoin, the next thing that comes to their mind is an investment opportunity, and not really the alternative currency Bitcoin was originally meant to be.

People who will consider the use of Bitcoin for daily transactions are those who consider their privacy. There are also those who are using it to bypass financial restrictions placed by government. I am also aware of some businesses that adopt Bitcoin payments for transnational trade payments.

Few reasons have limited the use of Bitcoin for day today transactions which includes volitility, government regulations, and seasonal high transaction fees.

How we have reached maximum adoption when there is only a few countries that have acknowledged bitcoin? There are 195 countries in the world and I do not need to look at the statistics to know that not even half of those have acknowledged bitcoin as a legal currency. We are still very far from the adoption we all have been hoping for.
Yes regulatory plays a huge part in why bitcoin is not yet being used for everyday transactions but I also think it is because a lot of us still think of bitcoin more as an investment and not as a currency we can and should use. Not to mention the very high transaction fees which prevent a lot of people from using bitcoin for mundane things.

There's still more significant room for growth, the more adoption it gets the more significant it even becomes and more reasons to grow because if this growth isn't affected it cannot adequately suit in for the adoptions, if bitcoin gets to the point it becomes a day to day methods of transaction which it currently is in some places, it will open opportunities for innovation , a typical example is in years ago, possibly 5 years down history, in the early years of bitcoin, it took a good number of times to confirm bitcoin transactions but now it takes a matter of minutes, some even as low as 10mins, that's actually an evolution for adaptability and with time when it further gets a wide range of incorporation into the economic activities of a good part of the big economy, more adaptable features will set in and even exchanges will begin to incorporate platforms that allows you spend your bitcoin like Fiat without hitches as confirmation at this point will be under 3-5 minutes possibly, all of this is possible. 

Why do you think there would t be further adoption? if there are spot ETF's in
operation and the US 'normalising" Bitcoin even further by considering
a reserve, why would it stop there?


What advantage does Bitcoin have over FIAT for buying a Coffee? Michael Saylor
points out that FIAT is a perfect medium for daily purchases but its a miserable vehicle
for investments and saving, Bitcoin is the opposite!

bitcoin is the currency of the future so bitcoin is free to be used as an investment asset and as a means of exchange.

for those who want to make bitcoin a means of transaction, of course they can use the smallest part of bitcoin, namely satoshi or mbtc. but for now transactions using the smallest unit of bitcoin for daily transactions are still not popular.

and for those who want to make bitcoin a hedge against money, they can buy bitcoin using the DCA method and store it in a personal wallet for an unspecified time.

so everything is a choice for each and bitcoin is both (investment asset and currency)

Does bitcoin even have a dead end? Things like bitcoin are genius innovations that we might see it keep developing over years or if not bitcoin itself then it could lead to more advancements when it comes to crypto. Will it be stagnant? I do not think so but let us see. For now, bitcoin still has a lot to show.
