That's true , but still lump-summing is also a nice method of purchasing Bitcoin, expecially when one have some good cash flow . Because most time it help to give some good head start in one investment . For instance one may have $1k( $500 is for covering expenses while the remaining is for investing) and the individual have some nice cashflow. So he or she can go all in with the $500 then may decide to start using DCAing after that . With that he or she will be able to coverup more ground in his Bitcoin accummulation, so most time making use of all the strategies actually nice , but if you see you can keep up you can stick with your normal DCAing.
I agree with you. This will help boosting the accumulation process especially as a starter before, then sticking to your plan and DCAing with the amount you are willing and capable to meet up with weekly, quarterly or monthly. The goal is to be aggressive in our buying but not exhausting oneself in the process and pesting on other funds just to meet up.
