AI is just a tool. Like any other, it does what its programmed to do. So, yeah, AI could totally start buying Bitcoin if its capable to. Think of it like a really smart calculator that can also buy stuff. But it doesnt have a mind of its own. If someone programs it to see Bitcoin as a good investment, it will buy it.
That's right. AI is a tool, at the end it is the user the one that decides what to do with the tool.
AI might try to predict the price of Bitcoin, but most probably it won't get it right, because there are many events that might change the price.
It's all new and exciting, but we still don't have General AI or a sentient organism.
