because DCA is slow in building your portfolio faster. If you lump sum, buy at the dip and keep your regular DCA ongoing while you use the other strategies once in a while when you can, you will definitely reach your bitcoin target faster than only using DCA method.
you can dca twice or more weekly or monthly and your portfolio will still move as fast as you want it. All you have to do is just to increase your dca amount and reduce your buying intervals.
Don't get this twisted mate, I have never seen a situation where DCA is made twice a week This is More like aggressive buying of bitcoin, and sure some guys has already calculated the distance of thier accumulation journey so what they do is to apply some aggressiveness so that it won't take longer than expected while some guys can also decide to front load their Investment due to some delay that may likely occur in the future.
and yeah sometimes is good to front load our investment since we still have the energy to do that because some day we might get demoted from job or get sacked due to some reasons and this may likely affect our accumulation journey, and some situation can even require pausing the accumulation journey for some time and start looking for possible way to figure things out so as to maintain the ongoing buying of bitcoin and this can probably take some time before a guy can get employed but if you have already front load your investment before this time is assume that you have covered the purchase of those weeks you're going to Skip. This are the advantages of buying aggressively.
