No one can say if when that resistance @ $30K will be break and I see your point it's important to see the market to pump strong if that $60K will be reach this year, as far as we see the market still having difficulty breaking $30K and there are times that it keep bouncing down and the fear with new investors are affected as they can quickly sell and lose portions of their investments. Hard to predict, but if you believe so then better to keep buying portion by portion, as if the market pump back then the benefits is decent.
We can always believe that the BTC price will be higher than $30k at some point in the future, the current market correction is according to the predictions that have been determined on the price chart, because BTC will definitely return to the $25k price circle after a significant increase from the beginning of this year, so buying DCA is very important in the market correction price and we can make some purchases below the current price if the market can decline in the next correction
