AI is NOT some independent entity that make decisions like that on its own. Folks need to STOP thinking of 'AI' as some kind of self-aware thing that makes decisions about ANYTHING on its own.

PEOPLE set the boundaries of what an AI program does and what it is using as references for the decisions it comes up with. It cannot and will not 'just start' buying anything on its own - a person tells an AI trading bot what to trade in be it fiat, crypto, gold, silver, stocks & bonds, etc.

Frankly it is no different than any other trading bot other than being able to look at a wider range of inputs to use in the decision making progress. If the bot has been programmed to generate maximum profits by trading among a myriad of things (as defined by a person) and BTC is currently the best bet then yes, it could 'buy on its own' but only because someone has programmed it to do that. Again - no different than any other bot.

Of couse! Any day now, AI will wake up, dump fiat and start stakcing sats like a true maxi. Next thing you know, it'll be running its own mining farm and flexin its cold storage on X haha! just wait for the ai to start hodling harder than humans! 

What an interesting thought, I actually have spent some time thinking about this before and often wondered is some AI would become sentient and try to accumulate money in order to conduct some evil plot to destroy humanity, you know kind of like in guardians of the galaxy movies or something but even that seems too SciFi to ever actually happen irl. Idk at the rate technology is progressing in 20 or 30 years time who knows where this path leads lol

Sorry to say this but this is rather a foolish or childish question to ask, Ai as we know are completely dependent on humans, and also will they continue to be dependent on humans for as long as they continue to exist as Ai, what this means is that they can not make or take any decision on their own without human interference or interaction, they cannot trade or invest in any asset without taking instructions and setups from human.

So in essence, Ai will only buy bitcoin when it's been instructed and programmed by a humans to do so, Ai can only predict the market based on how it is trained, but can't make any formal trading or investing.

The question is not "Could AI do this?". The real question is "When will AI start doing this?". I'm sure that AI trading bots will become a thing in the next months or years. The current AI models are not self-aware right now, but super-AI will become self-aware in the near future.
Bitcoin is not a safe asset. Bitcoin is a risky and volatile asset, which can bring higher profits to speculative investors. The AI trading bots could invest in BTC and add it to aggressive and dynamic investment portfolios.
I don't think that AI is going to compare BTC to fiat. Bitcoin is a deflationary financial asset, while fiat currencies are inflationary by design.

AI would do so only if he is instructed properly, or because his data knowledge suggests to do so, just like others mentioned.

This was the case for a while, though it's not anymore. There are AI agents/operators that yes, will follow initial rules, though can learn, research and trade themselves. It's a concept that already works on platforms like virtuals and vvaifu, and is developing at a rapid rate. I'd say that they're not at the stage of being better than any algorithm developed and managed by a professional, though the concept is working and it has the potential to get there.

AI could buy bitcoin if it is programmed to do so based on market trends but it still depends on how it is set up by the developer and the data it uses

AI can learn and store information these days though that does not mean it's flawless. People often misconceive that AI is some super intelligence that is able to do everything perfectly, however it's not a super intelligence, it's an artificial one. That aside, automation has been around for a long time, AI has been working and developing at a exponential rate in the last two years, AI agents and operators that can learn and perform things like trading on their own is not as crazy of a phenomena as it sounds. Though again, whether it does a good job or not, or if you want to trust AI with your capital, are two different stories.

If you can't believe it, go and see it. Just search "Ai agents that can trade". There are projects that have these functions working live. I listed two in my post and there are many others. It became a reality around the end of last year.

@OP, AIs doesn't have their self will power, don't forget that they are just programs that is still developed by the knowledge of man which means that they don't act on their self will, they work and function under the commands and instructions which they have received via their programs and code by their developers.

In other way around, AI is already buying Bitcoin and other coin tokens too that a user have set instructions for them to buy, if you want to confirm, check some tier 1 exchange, you will discover that their are some inbuilt bots on those exchange that you could set a command for them to buy some Bitcoin at a certain price on your behalf, and after you have given the AI bots such command, even if you are not online or perhaps when you are sleeping and price gets to that level that you set it to buy, the bot will evacuate the buy or sell oder for you. @Op, if that is what you also mean, then AI are already doing it.
