It may not matter a whole hell of a lot if you buy the dip or not, especially if you might be receiving an income every week, and then there can be questions about the extent to which you hold back some of your discretionary income in order to wait for price dips that may or may not end up happening. Waiting for price dips likely puts a bitcoin investor in a wrong mentality, even though surely there could be some psychological pleasure that comes from holding back some value for dips... while recognizing and appreciating that the dips may or may not end up happening.
The price of Bitcoin of a truth is very unpredictable but considering the past events in the Bitcoin market, buying Bitcoin when there's a dip have in most times been very profitable to investors. It's important for investors to have it at the back of their minds that buying dips doesn't guarantee profits but the truth is that it's more advantageous than buying when the market is experiencing uptrend movement in price. In as much as I agree with you that waiting for dips have it's own mental pressures I also want you to come to terms with the fact that it's better to always buy dips than buying when the market is on the high.
Buying dips to me will always be the perfect moments of investing in Bitcoin and unless the market leaves me with results to think otherwise, I'll continue to stick with that
Choice of investment strategy really is a personal choice and what works for you might not necessarily work for another, and while I have not problems with buying the DIP, I don't think it should be your only investment strategy, Scaling and/or DCA should also always be a part of any investors strategy as it let's you invest on a regular rather than waiting for a dip all the time, waiting can be dangerous and
had I known ultimately becomes the motto of any investor who missed investment chances while waiting for a dip that didn't happen.
