was wondering what’s the point of btc? I’m just stating out

I bought around 50$ of btc as I’m literally just getting into stocks and crypto but i don’t understand what’s the point of it? Like I bought 50$ worth as right now it’s -18% or whatever, so i could still buy 50$ worth when its +20 for example so what’s the point of buying it at this low? How much money can btc even make you? I am so confused ive done research but I have so many questions CAN ANYONE HELP
