New to investing with 600k

600k is all I have to invest, first time dipping my toes into the stock market. Originally was just planning to go all into S&P500 and hold forever. But stumbled upon this subreddit and now I am unsure if I should outright lump sum buy 1BTC now to just hold forever while all remaining and future money goes into S&P500. Maybe DCAing 1BTC is better but with how quick the price rises it may take years (or maybe never) to catch up to 1BTC. Am I being too risky? I just want to cap at 1BTC because I am not a risk taker (previously all my investments were in bonds lol cos I was too scared to touch equities but forcing myself to step out of my comfort zone now because I know that is the right move).

Also I want to buy ETF because I am too scared to keep it in a wallet.
