People are going to get killed on alts. They see the ALT/BTC chart and see #moon and #lambos; but they forget that BTC/USD is tanking at the same time. So the ALT/USD price is effectively the same, and you're just setting yourself up for a world of hurt. Always, always, always think of your ALT transactions in USD/your-fiat; and try to buy ALTs with USD/your-fiat unless your goal is to horde BTC and go long.
