A real investor will never wait for a fall to buy DIP. If you are waiting for a fall to buy DIP, then you are probably short-term investing. Because a real investor will never wait for a fall. He will buy continuously by relying on his net income or his money.
This is wrong, deploying waiting for the dip as your accumulation strategy isn't wrong if you're already close to your accumulation target and still have a good timeframe away from your holding period expiration, you can choose to accumulate your buying funds and target dips to but a bigger quantity at Lowe's prices and keep closing in on your accumulation target at a faster pace. Although myself would love consistent buying regardless and saving up for dip purchases separately, but the investor in my description that chooses to employ only buying the dip at his status is still a very much real investor.
Where waiting for the dip becomes a bad practice is when it's practiced by a low-coiner or a no-coiner. People who don't have BTC and people who are still very far from their accumulation target should continue buying consistently, and with as much aggressiveness as possible in order to accumulate a decent stash of BTC.
