1 BTC? if you can't afford then simply start on stacking just sats, I think if you are thinking of getting a whole bitcoin then it will be out of reach for us majority here. That's why for me, just invest what you can afford, you can't start from $50-$500 or set aside monthly money coming from your salary to put into bitcoin, simply as that.

Investing is not that complicated, the problem is that people wanted to get rich very quick. You say it's expensive today, but you are going to miss the boat if it goes 6 digits in the next year or 2.
