You could also find some of the lottery winners that absolutely hated what happened to their lives after they won and win the draw right before their ticket would have won.

That way you spare them the misery that the money brought them and you get a nice chunk of change for yourself in the process.

Now, here's the thing. I'd say you would be sharing those winnings with the original winner unless you prevented them from getting the ticket

The January 2nd Powerball draw was not won by anyone and paid $39M.

That's plenty of seed money to invest in Google, Bitcoin, et al with perfect knowledge of stock trends. Even if it's only short term knowledge due to breaking from the original timeline, you could easily grow your investment into the billions overnight.

Perhaps the most amazing stock of the year was Xcelera.com, formerly known as Scandinavia. Once a closed-end fund specializing in Scandinavian stocks, and then an operating company that owned a hotel in the Canary Islands, it made a small investment in an Internet company last year. Before it disclosed that investment, the family of Alexander Vik, the company's chief executive, was given options to buy a million shares of stock, at a price of $3.25 each. The shares ended 1998 at $3.75, or $1.25 adjusted for two subsequent splits. They ended 1999 at $139.50, an increase of 11,060 percent. The Viks' option position is now valued at $415 million.

If a bunch of you's from another timeline can come too, that opens the door to more interesting shenanigans anyway, like if they all get unique valid IDs, one of you could run for political office and get enough alternative selves to come back and vote for them to win. Or get different versions of yourself to run for all the political offices in a given area while bringing enough copies to win all their elections, and completely dominate the politics of the area by having everyone in office have the same or very similar views.
