mindrust, don't invest more than you're ready to lose.

Don't want to sound like a bear or a party poop as someone would say - I'm far from both positions as should be clear to anyone following this thread - but hard times do happen, it's best to be "pee pared" as the same someone would put it ;-)

TL;DR don't overdo it. DCA with the occasional BTFD spree is fine.
