A good mix is good but I’ll still say in 70% of those situations Dollar Cost Average has the best results.
DCA gives the best results overtime because it enables you to be constantly buying bitcoin gradually overtime and you will be able to accumulate a good size of bitcoin that ordinarily you wouldn't have been able to accumulate with DCA. Come to think of it, I believe that mixing the three strategies together in your bitcoin accumulation journey gives the best results 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.
I think people who can afford to lump sum and wouldn’t mind are those who have gone far in their bitcoin accumulation or those who have a lot of discretionary money at their disposal and is still accumulating consistently and aggressively as possible on the DCA.
No it is not compulsory that you must have gone far in your bitcoin investment or have huge discretionary income in your possession before you can lump sum. You can choose to lump sum with any amount of money that you have because you are buying right away and the most important thing is that you shouldn't stop your DCA because you want to lump sum.
Last week, I got an extra cash of $100 from my colleague at work after a project was executed, I never expected the money neither do I have any urgent need for the money so what I did was to lump sum with it despite that I just bought my weekly bitcoin the previous day.
Just like the figure that JJG used $5000. I can choose to lump sum with $1000 right away as a new investor who just want to start his bitcoin investment at has $5000 on ground as my discretionary income. I can use $2500 for weekly DCA by spreading it out in various weeks and use $700 to keep for buying at the dip and add the remaining $800 to my emergency funds while I continue building it.
