Historically in bitcoin, in a year's time, there are always dips, even if the year happens to be a bullrun year - however, I probably agree with both you ginsan and with RewFrew (you guys don't seem to be saying anything much different from one another), that there may well be times in which whatever dip that we are experiencing might end up being all the dip that we are going to end up getting, and the dip might not end up getting any lower than the current price.. yet when we are in such situations, we are hardly ever really going to have a lot of realistic and accurate information to conclusively know if the BTC price is going to dip any further within this streak (correction) or not.
That is the volatility in Bitcoin DCA value, its always unstable and there is the possibility to have a bear market and a bull market in the same cycle let's say in the 1-year range we see multiple times when Bitcoin change its direction in price and this has been the market sentiment over the years and that is not going to change since it the nature of the market, bitcoin is designed to remain volatile in price and that is what makes it a speculative asset.
This market volatility can be beneficial to both long-term and short-term Bitcoin holders if they know when to take profits or cut losses the ability to make that decision accurately is what makes the difference in the percentage profits that come along with holding Bitcoin.
Even though no one can speculate on the direction Bitcoin will go in whatever price trend either in a dip or bull run Bitcoin market, the ability to make a proper Dollar cost of Bitcoin in whatever price trend will away put the investors in a profitable position.
