Most of this guy's that wait for the dip before buying thinks it's the best way to maximize profit because most of them has this mindset of buying low and selling high, so they wait for the market to dip before buying, not knowing that it's the wrong approach to Bitcoin investment, a Bitcoin investor that is only thinking long term should be buying anytime his discretionary income is available irrespective of it current price, because in the future this current price would be a bargain comparing to how high the value of Bitcoin might has rise up to.
I believe people who are waiting to buy the dip are short term investors (more like traders) who are only after profit so they believe buying cheap and selling after a little price movement is the best way.
You are very wrong in this because buying the dip is not for only short-term investors. There is nothing wrong with buying the dips like this thread suggested. It is even smart investors that accumulate more bitcoin during dips when others are shaking and selling in fear. Buying the dips is a wonderful time to buy bitcoin and hold for long because you will be collecting more bitcoin for the same amount of money than when the price was higher. Most of my finest purchases were made during the dips but that does not mean I stop buying when price is rising because I combine the DCA method with buying the dips and it has been working out very fine for me. Don't discourage anyone who decides to allocate part of his investment funds into buying the dips while still letting the DCA purchase run unhindered.
