Nice one. Though it should be pretty basic, people are having a hard time following what you've stated there dude because emotions can easily take over when you see your money dwindling down. The part where you shouldn't invest what you can't lose is probably the best answer to those people panicking when the market is bearish. It's not an overnight thing guys.
Well some people just dont have a choice. They might have bills to pay and other needs, HODLing is just not an option for them
