What would you do if you were transported to January 2013?
I would:
Buy $2,000 worth of Tesla stock at $30, sell at $250 in March 2014. Profit = $17,000
Buy $2,000 worth of bitcoins at $13, sell at $1200 in November. Profit = $200,000
Buy $2,000 worth of litecoins at $0.07, sell at $48 in November. Profit = $1,400,000!!
Then I would retire.
Instead, being the idiot that I am, I did the following:
Bought 1 year of college education for $6,000, unable to sell. Profit = $0.
