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
Nobody is saying that when you buy bitcoin at the dip, it wouldn't give your a bigger profit compared from when you buy higher. But the problem lies in your waiting for the dip without buying any bitcoin. Waiting is very dangerous and it's a success stealer which makes it not a good accumulation practice for new investors and low coiners.
If you want to start using profits to make decisions on which strategy to use, you will feel buying at the dip is the best but it isn't, because in the long run it is the quantity of bitcoin in your portfolio that will determine your profits. Someone with 3btc will be in more profits than someone with 1btc. This is why you don't need to wait for the dip before buying because it will slow down your accumulation pace. It's better you stick to DCA method because it enables you to buy bitcoin every week regularly with an amount from your discretionary income that will allow you to be consistent and persistent in buying bitcoin regularly 4-10 years and above.
Most investors that do plan to buy at the dip ends up procrastinating because they will want the price to dip to their own price and most times, it doesn't. Don't wait for unpredictable scenarios before investing in bitcoin for a long-term to transform your financial status to a better one.
