In 2002 buy apple or google stock then use that money to buy bitcoin.

you'd be waiting several years. bitcoin wasn't "invented" until '08. but you're on the right track. by '09, you could have got 100btc for lunch money. sold today it would give you more than enough to live on.

In 2002 there were no bitcoins. But there were Epstein island parties

You could travel back to 2009 and impersonate Satoshi Nakamoto. There are already conspiracy theories that Nakamoto is a time traveler because he did what a time traveler might do. He anonymously created Bitcoin, and then he disappeared. He has tens of billions of dollars of bitcoin sitting there unused. Or maybe it's just waiting until he gets back to his time.
