I'm asking because I've seen a lot of predictions suggesting that it might hit $100,000 some time this decade and was hoping to try to gauge how realistic people think these sort of predictions might be?
There are quite a lot of things you're going to see on the internet about Bitcoin, many of which aren't true and not reliable, plus shouldn't be a reason to join/not join the network. I don't know if the predictions we see are plausible, but if you're going to invest in this network, I want to update you with this rule of thumb: "invest only what you can afford to lose", what that means is do not go on to invest in Bitcoin with all your funds cause people have predicted it getting to over $100,000.
Bitcoin is a speculative market, and this predictions are meant to be seen, many users who have taken this sort of predictions to heart and invested of it are the ones always shaken by FUD when there's a plunge, no matter how little. Take your time to understand btc price movements/history and more about the network, that way you'll be able to make decisions yourself without having to look to the internet.
