Smart side hustle that is proven to work

NASDAQ:CRON   Cronos Group Inc. Common Share
I normally don't make such videos but for whatever reason, I just wanted to share with you guys about the side hustle that i learnt of one of my LATE Granddad. Buy Low, Sell high. Buy some cheap Stocks at a low price and forget about it. 10, 15 years down the line, you will thank yourself.
Comment: Forgot to mention that some of these companies pay you a part of their earning as well as dividends. so that's a bonus.
