Investing advice (S&P100, S&P500, Bitcoin)

Hey Investors! I’m kinda new to it, once upon a time I watched introduction course to investments. After it, I bought a share in Virgin Galactic, which went to hell.

I have some savings (around 20k$), and I was thinking about finding a better place for them rather than leaving on the bank account.

My Idea was to invest 1/3 into the S&P 100, 1/3 into the S&P 500, and 1/3 into Bitcoin.

I need your advice, if I should do that? Or should I rather pass any course or something to make a balanced decision?

Thanks!
