I would also add to the list: Get out of bad trades as quickly as possible, don't wait for them to turn around. A single bad trade can wipe out dozens of good ones if you're not careful.

You can also trade on 5 minute charts for strong coins, but you need to be quick on your toes. I found those ones were good for training wheels, because the turnaround is fast enough to remember what you were thinking when you placed the bid, and then watch the progression, and get out quickly so you're not stressing for a day waiting for the bounce. Trade small amounts and take profits just above break-even to stay safe and build confidence, but pay attention to how often you could have let it ride a little longer for more profit.

Most important: Never go all-in! Trading is not gambling, because you're not trying to win big on a single bet. Successful trading is about repeated trades with modest profits and small losses. It's not a get-rich-quick scheme, it's a job.
