I would buy lots of salt, travel to 1561 (Inka-Gold Rush) sell all the salt and buy gold for it. I would then sink the gold into a deep trench and retrieve it back in 2011.
i thought about reading stories like harry potter or watching movies and then just go back in time and write/do them then and claim them as my own. i think it would be easy to do. also you could just tell them the future. you could also just charge money for the time machine XP
i would never use a time machine to get rich. But I have too I would win the lottery, go into stocks, and make sure I get the gold from my great great great grandfather.
I would gather as much gold as I can and put it in a box. I would then take that box, go back in time, and hide the box. When I get back to the present day, I would gather even more gold into the box, go back in time, and repeat the process.
Sadly, I've actually given this one some thought. Option 1: Go back in time, do some of the great money making novels, albums, inventions, etc. before they were written, claim them as my own. Option 2: Go back in time before stock market crashes like the Great Depression and the housing crash, start a hedge fund, and sell short everything that is going to fall. Option 3: Start charging $$ to predict the future. Option 4: Take a bunch of guns/tanks/etc back in time to the 1600s or so. Become ruler of all the world, make everyone pay me massive tithings and everything they have, then go forward in time again to present day. Option 5: Use the winning lottery numbers over and over that I know will win. Funny, almost all of these options involve screwing over at least one person at some point in time...
#1 Go back in time, buy some antique (they wont be antique back then, though) items, and go back to the future and sell them there.
#2 The antique items didn't sell for enough? Go back a couple of decades and buy a crapload of stocks in computer companies with the money you just earned or some other stocks you know will increase in value.
#3 ???
#4 Profit.

Alternatively, you could charge ridiculous amounts from people wanting to change something in their past. For example, someone pays you a million dollars and you travel back in time and warn him not to push that big red button labelled "DO NOT PUSH!".
Take your payment up front, because otherwise the time line will be messed up and he wont remember ever having asked you for help (because he never had to ask).

This all sound too complicated or slow? I got the perfect solution!
Put all your money in a box. Travel back in time five seconds with the box. Tell past you to put his money in the box too. Travel back five more seconds. Rince and repeat, until you're ready to return to one second after you first disappeared (we don't want multiple yous to exist. They'd want a share!)
Buy crack cocaine. Go back in time. Sell. Use secret of crack making to create a financial empire. Then, when the future rolls around, you'll be the one selling all the crack.
