<prompt> Human: Im a student who has 700... How can I double that over summmer? Cryptos? Investing? Betting? etc Thanks!  <response>: 700 isnt enough to invest, and cryptos are the same actually probably worse than betting.In short, there is no safe way to double money over the summer through investing or gambling. If there was everyone would be doing it.The best way to double it is to go get a job and earn another 700.
